Lu, Shang-Yuan published the artcilePyridinylidenaminophosphines as Versatile Organocatalysts for CO2 Transformations into Value-Added Chemicals, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is cyclic carbonate formyl amine preparation pyridinylidenaminophosphine catalyst.

The carboxylative cyclization of propargylic alcs. with CO2 was developed employing pyridinylidenaminophosphines (PYA-Ps) as organocatalyts for the first time. Moderate to good yields of α-methylene cyclic carbonates were obtained with excellent chemo- and stereo-selectivity. D. functional theory (DFT) calculations reveal that the catalytic reaction tends to proceed via the pyridinylidenaminophosphines-mediated basic ionic pair mechanism, and the intramol. cyclization should be the rate determining step. Furthermore, the catalytic diversity of PYA-Ps was investigated for the chem. transformations of CO2 to functionalized cyclic carbonates and N-formylated amines.

Huang, Wenbo published the artcileSynthesis of Multisubstituted Pyrroles from Enolizable Aldehydes and Primary Amines Promoted by Iodine, Name: 5-Methyl-2-phenylhex-2-enal, the main research area is pyrrole preparation enolizable aldehyde amine iodine.

1,2,4-Trisubstituted pyrroles were synthesized from enolizable aliphatic aldehydes and primary aliphatic amines by using iodine as the dual Lewis acid/mild oxidant. In the presence of 3.0 equiv of TBHP, enolizable α,β-unsaturated aldehyde, for example, cocal reacted with aromatic primary amines to form C2-iodized N-arylpyrroles. An acetal-containing pyrrole was successfully prepared from 4-aminobutyraldehyde di-Et acetal, which can be converted easily to 5,6,7,8-tetrahydroindolizine derivatives

Lux, Marcel published the artcileAdditions of Aldehyde-Derived Radicals and Nucleophilic N-Alkylindoles to Styrenes by Photoredox Catalysis, Product Details of C8H10O2, the main research area is photoredox catalyzed addition acyl radical alkylindole nucleophile styrene.

The consecutive addition of acyl radicals and N-alkylindole nucleophiles to styrenes was established, as well as some addnl. radical-nucleophile combinations. Both aryl and aliphatic aldehydes give reasonable yields. The reaction proceeds best for α-substituted styrenes, effectively creating a quaternary all-carbon center. Some iridium-based photoredox systems are catalytically active; furthermore, a base is needed in this transformation. Radicals are formed by reductive perester cleavage and hydrogen atom transfer.

The three-component reaction between a resorcinol, 1,3-dimethoxybenzene and alkyl aldehydes RCHO (R = Me, Et, iso-Pr, Bu, cyclohexyl, etc.) along with BF3.OEt2 affords a C2v-sym. resorcin[4]arene tetraethers I (R1 = H, Cl, Br, Me, OH; R2 = H, OH, Me, OMe) in one step; in most cases, the single isomer can be precipitated from the reaction mixture in moderate to excellent yields (up to 89%). The reaction is tolerant of 2-substituted resorcinols (R1 = OH, Cl, Br, Me), allowing a third type of functionality to be regioselectively incorporated during the macrocyclization.

Liu, Jiangjun published the artcileNickel-Catalyzed Intramolecular Desulfitative C-N Coupling: A Synthesis of Aromatic Amines, Product Details of C8H11NO, the main research area is aryl sulfonamide preparation nickel catalyst desulfonylative coupling; aromatic amine preparation.

A nickel-catalyzed intramol. C-N coupling reaction via SO2 extrusion was presented. The use of a catalytic amount of BPh3 allowed the transformation to take place under much milder conditions (60°C) than previously reported C-N coupling reactions by CO or CO2 extrusion (160-180°C). In addition, this method displayed good functional group tolerance and versatility, as it can be applied to the synthesis of dialkyl aryl amines, alkyl diaryl amines and triaryl amines. The robustness of the desulfitative C-N coupling was demonstrated by three high-yielding gram-scale reactions.
