Lipp, Alexander published the artcileCatalyst-Free Decarbonylative Trifluoromethylthiolation Enabled by Electron Donor-Acceptor Complex Photoactivation, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is aldehyde acyl dihydropyridine trifluoromethylthiolation electron donor acceptor light DFT; trifluoromethylthio ether preparation; aldehydes; density functional calculations; electron donor-acceptor complexes; photocatalysis; radical reactions; trifluoromethylthiolation.

A catalyst- and additive-free decarbonylative trifluoromethylthiolation of aldehyde feedstocks has been developed. This operationally simple, scalable, and open-to-air transformation is driven by the selective photoexcitation of electron donor-acceptor (EDA) complexes, stemming from the association of 1,4-dihydropyridines (donor) with N-(trifluoromethylthio)phthalimide (acceptor), to trigger intermol. single-electron transfer events under ambient- and visible light-promoted conditions. Extension to other electron acceptors enables the synthesis of thiocyanates and thioesters, as well as the difunctionalization of [1.1.1]propellane. The mechanistic intricacies of this photochem. paradigm are elucidated through a combination of exptl. efforts and high-level quantum mech. calculations [dispersion-corrected (U)DFT, DLPNO-CCSD(T), and TD-DFT]. This comprehensive study highlights the necessity for EDA complexation for efficient alkyl radical generation. Computation of subsequent ground state pathways reveals that SH2 addition of the alkyl radical to the intermediate radical EDA complex is extremely exergonic and results in a charge transfer event from the dihydropyridine donor to the N-(trifluoromethylthio)phthalimide acceptor of the EDA complex. Exptl. and computational results further suggest that product formation also occurs via SH2 reaction of alkyl radicals with 1,2-bis(trifluoromethyl)disulfane, generated in-situ through combination of thiyl radicals.

Dong, Jianyang published the artcileFormyl-selective deuteration of aldehydes with D2O via synergistic organic and photoredox catalysis, Application In Synthesis of 1205-17-0, the main research area is aldehyde deuterium oxide tetrabutylammonium decatungstate thiol photocatalyst selective deuteration; deuterated aldehyde preparation.

Huang, Mouxin published the artcileDeracemization through photochemical E/Z isomerization of enamines, Application of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is aldehyde enamine deracemization; photosensitizer aminocatalyst isomerization.

Catalytic deracemization of α-branched aldehydes is a direct strategy to construct enantiopure α-tertiary carbonyls, which are essential to pharmaceutical applications. Here, authors report a photochem. E/Z isomerization strategy for the deracemization of α-branched aldehydes by using simple aminocatalysts and readily available photosensitizers. A variety of racemic α-branched aldehydes could be directly transformed into either enantiomer with high selectivity. Rapid photodynamic E/Z isomerization and highly stereospecific iminium/enamine tautomerization are two key factors that underlie the enantioenrichment. This study presents a distinctive photochem. E/Z isomerization strategy for externally tuning enamine catalysis.

Silva Teixeira, Carla S. published the artcileStudying Haloanisoles Interaction with Olfactory Receptors, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is odorant haloanisole olfactory receptor association docking mol dynamic simulation; Haloanisoles; homology; molecular docking; molecular dynamics; olfactory receptors.

In this paper, computational means were used to explain and predict the interaction of several odorant mols., including three haloanisoles, 2,4,6-trichloroanisole (TCA), 2,4,6-tribromoanisole (TBA), and 2,4,6-trichlorophenol (TCP), with three olfactory receptors (ORs): OR1A1, OR1A2, and OR3A1. As the X-ray structure of these ORs is not known, the three-dimensional structure of each OR was modeled by homol. modeling. The structures of these ORs were stabilized by mol. dynamic simulations and the complexes of the odorant mols. with each ORs were generated by mol. docking. The theor. results have shown that each OR has distinct but well-defined binding regions for each type of odorant mols. (aldehydes and alcs.). In OR3A1, the aldehydes bind in the bottom region of the binding pocket nearby Ser257 and Thr249. In the paralogues OR1A1 and OR1A2, the aldehydes tend to interact in the top region of the binding pocket and close to a pos. charged lysine. On the other hand, the alcs. interact in the bottom region of the active site and close to a neg. charged aspartate. These results indicate that when aldehydes and alcs. odorants compete in these two ORs, the aldehydes can block the access of the alcs. odorants to their specific binding site. This observation goes in line with the exptl. data that reveals that when the odorant is an aldehyde, a lower quantity of ligand is needed to cause 50% of the maximum response (lower EC50), when compared with the alcs. The theor. results have also allowed to explain the differences in the activity of (S)-(-)-citronellol in the wild-type and mutated OR1A1. The theor. results show that Asn109 has a preponderant role in this matter, since when it is mutated, it leads to a conformational rearrangement of the binding pocket that prevents the interaction of (S)-(-)-citronellol with Asp111 that was shown to be important for the OR activation. The good agreement between the theor. and exptl. results also lead us to study the potential interaction of the haloanisoles, TCA, TBA, and TCP with these ORs. The results have shown that these compounds can compete with other known agonists/antagonists for the access to the binding regions of ORs. These results may partially explain the capability of these compounds to give a musty odor to food and beverages at very low concentrations

Laufersweiler, Michael C. published the artcileCorrelation of chemical structure with reproductive and developmental toxicity as it relates to the use of the threshold of toxicological concern, Formula: C11H12O3, the main research area is structure toxicity correlation reproduction development threshold toxicol.

In the absence of toxicol. data on a chem., the threshold of toxicol. concern (TTC) approach provides a system to estimate a conservative exposure below which there is a low probability of risk for adverse health effects. The original toxicol. dataset underlying the TTC was based on NOELs from repeat dose studies. Subsequently there have been several efforts to assess whether or not these limits are also protective for reproductive/developmental effects. This work expands the database of chems. with reproductive and developmental data, presents these data in a comprehensive and transparent format and groups the chems. according to the TTC “”Cramer Class”” rules. Distributions of NOAELs from each of these classes were used to assess whether the previously proposed TTC values based on repeat dose data are protective for reproductive/developmental toxicity endpoints as well. The present anal. indicates that, for each Cramer Class, the reproductive and developmental endpoints would be protected at the corresponding general TTC tiers derived by .

Kapoor, Mohit published the artcile77Carbon Dioxide-Mediated C(sp2)-H Arylation of Primary and Secondary Benzylamines, Safety of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is benzylamine aryl iodide carbon dioxide palladium regioselective arylation catalyst; arylbenzylamine ortho preparation.

C-C bond formation by transition metal-catalyzed C-H activation has become an important strategy to fabricate new bonds in a rapid fashion. Despite the pharmacol. importance of ortho-arylbenzylamines, however, effective ortho-C-C bond formation of free primary and secondary benzylamines using PdII remains an outstanding challenge. Presented herein is a new strategy for constructing ortho-arylated primary and secondary benzylamines mediated by carbon dioxide (CO2). The use of CO2 with Pd is critical to allowing this transformation to proceed under relatively mild conditions, and mechanistic studies indicate that it (CO2) is directly involved in the rate-determining step. Furthermore, the milder temperatures furnish free amine products that can be directly used or elaborated without the need for deprotection. In cases where diarylation is possible, an interesting chelate effect is shown to facilitate selective monoarylation.
