Highly enantioselective organocatalytic sulfa-michael addition to α, β-unsaturated ketones
Rana, Nirmal K.,Selvakumar, Sermadurai,Singh, Vinod K.
supporting information; experimental part, p. 2089 - 2091 (2010/06/16)
"Chemical Equation Presented" A cinchona alkaloid-derived urea was found to be an efficient organocatalyst for catalyzing enantioselective conjugate addition between thiols and various α,β-unsaturated ketones to provide optically active sulfides with high
Asymmetrie ruthenium-catalyzed 1,4-additions of aryl thiols to enones
Badoiu, Andrei,Bernardinelli, Gerald,Besnard, Celine,Peter Kuendig
supporting information; experimental part, p. 193 - 200 (2010/04/25)
Well defined, stable, one-point binding ruthenium complexes 1 and 2 selectively bind and activate α,β-unsaturated carbonyl compounds for cycloaddition reactions. These mild Lewis acids catalyze asymmetric 1,4-addition reactions of aryl thiols to enones wi
Synthesis and resolution of a multifunctional inherently chiral calix[4]arene with an ABCD substitution pattern at the wide rim: The effect of a multifunctional structure in the organocatalyst on enantioselectivity in asymmetric reactions
Shirakawa, Seiji,Kimura, Tomohiro,Murata, Shun-Ichi,Shimizu, Shoichi
experimental part, p. 1288 - 1296 (2009/06/28)
An efficient synthetic route to inherently chiral calix[4]arenes with an ABCD substitution pattern at the wide rim in the cone conformation was developed for the first time. For the synthesis of inherently chiral ABCD-type calix[4]arenes, first 5,11-dibro
Addition of Aromatic Thiols to Conjugated Cycloalkenones, Catalyzed by Chiral β-Hydroxy Amines. A Mechanistic Study on Homogeneous Catalytic Asymmetric Synthesis
Hiemstra, Henk,Wynberg, Hans
, p. 417 - 430 (2007/10/02)
Reactions between aromatic thiols and conjugated cycloalkenones afford optically active 3-arylthiocycloalkanones, when chiral bases are used as catalysts.This paper reports a detailed investigation into the mechanism of this catalytic asymmetric synthesis
