Ruyet, Louise published the artcileZ-Selective Pd-catalyzed 2,2,2-trifluoroethylation of acrylamides at room temperature, Synthetic Route of 104-01-8, the main research area is quinolinyl acrylamide trifluoroethyl mesityliodonium trifluoromethanesulfonate palladium catalyst diastereoselective trifluoroethylation; quinolyl trifluoropentenamide preparation.

A straightforward 2,2,2-trifluoroethylation of acrylamides by Pd-catalyzed C-H bond activation was reported by using a fluorinated hypervalent iodine reagent as a coupling partner. At room temperature, this additive-free approach allowed the synthesis of Z-2,2,2-trifluoroethylated acrylamides (19 examples, up to 73% yield) in a stereoselective manner. Under these mild reaction conditions, the methodol. turned out to be functional group tolerant and mechanistic studies gave us a better understanding of the transformation.

Gaspar, Francisco V. published the artcileEnantioselective Synthesis of Isoflavanones and Pterocarpans through a RuII-Catalyzed ATH-DKR of Isoflavones, Related Products of isoquinoline, the main research area is pterocarpan isoflavanone enantioselective preparation; isoflavone ruthenium catalyzed ATH DKR.

Noyori-Ikariya RuII complexes promoted the one-pot C=C/C=O bonds reduction of isoflavones using sodium formate as the hydrogen source through asym. transfer hydrogenation-dynamic kinetic resolution (ATH-DKR). Due to the neutral conditions employed, isoflavones with different substituents at the 2′-position of B-ring (H, OH, OMe and Br) were successfully reduced. Ten cis-3-phenylchroman-4-ols were selectively obtained (>20 : 1 dr) in good yields (up to 86%) and excellent enantioselectivities (up to >99 : 1 er). The synthetic applications of these chiral compounds were also demonstrated. Enantioenriched isoflavanones were obtained under mild metal-free oxidation of the cis-3-phenylchroman-4-ols while pterocarpans were synthesized by two strategies: an acid-catalyzed cyclization and a novel approach based on a Pd-catalyzed C-O intramol. cross-coupling reaction.

Wu, Xiaopeng published the artcileDecarboxylative acylation of carboxylic acids: reaction investigation and mechanistic study, HPLC of Formula: 104-01-8, the main research area is aromatic aliphatic ketone preparation photochem one pot; carboxylic acid aromatic aliphatic thioester decarboxylative acylation.

Ketones serve as one of the most critical building blocks in organic synthesis, involving numerous functional group transformations. Herein, authors report an unprecedented photoredox-nickel metallaphotoredox-catalyzed decarboxylative acylation of common aliphatic acids with readily available aromatic and aliphatic thioesters. A wide range of structurally diverse asym. aryl alkyl and dialkyl ketones have been constructed in yields of up to 98% with this strategy. The protocol has excellent reaction selectivity and functional group compatibility, representing a significant step forward in ketone synthesis. The one-pot decarboxylative acylation at the gram scale from two different carboxylic acids and the late-stage application for the synthesis of complex ketones shows its synthetic robustness. Both mechanistic experiments and d. functional theory (DFT) calculations suggest that the decarboxylative acylation reaction operates via an underdeveloped Ni(I)-Ni(II)-Ni(I)-Ni(III)-Ni(I) catalytic cycle.

McLaughlin, Calum published the artcileBase-free Enantioselective C(1)-Ammonium Enolate Catalysis Exploiting Aryloxides: A Synthetic and Mechanistic Study, COA of Formula: C9H10O3, the main research area is base free enantioselective ammonium enolate isothiourea catalysis aryloxide; Michael addition aryl ester vinyl bissulfone; VTNA; enantioselective Michael addition; inverse secondary kinetic isotope effect; isothiourea catalysis; mechanistic analysis.

An isothiourea-catalyzed enantioselective Michael addition of aryl ester pronucleophiles to vinyl bis-sulfones via C(1)-ammonium enolate intermediates has been developed. This operationally simple method allows the base-free functionalization of aryl esters to form α-functionalized products containing two contiguous tertiary stereogenic centers in excellent yield and stereoselectivity (all ≥99:1 er). Key to the success of this methodol. is the multifunctional role of the aryloxide, which operates as a leaving group, Bronsted base, Bronsted acid and Lewis base within the catalytic cycle. Comprehensive mechanistic studies, including variable time normalization anal. (VTNA) and isotopologue competition experiments, have been carried out. These studies have identified (i) orders of all reactants; (ii) a turnover-limiting Michael addition step, (iii) product inhibition, (iv) the catalyst resting state and (v) catalyst deactivation through protonation.

Metal carbenes, derived from the decomposition of diazo compounds, are valued for their capacity to perform a variety of transformations. A unique class of acyclic, bis-diazo compounds, the donor-acceptor-acceptor 1,3-bisdiazo compounds, are described herein. These compounds are available from acyclic β-keto esters and especially reactive at the donor-acceptor diazo unit. These bisdiazo compounds react smoothly with rhodium acetate and alcs. to give monodiazo, cyclic orthoesters, presumably through the capture of a transient oxonium ylide.
