Sobhani, Sara; Fielenbach, Doris; Marigo, Mauro; Wabnitz, Tobias C.; Joergensen, Karl Anker published the artcile< Direct organocatalytic asymmetric α-sulfenylation of activated C-H bonds in lactones, lactams, and β-dicarbonyl compounds>, SDS of cas: 112-63-0, the main research area is cinchona alkaloid catalyst stereoselective sulfenylation lactone lactam dicarbonyl compound.
The application of cinchona alkaloid derivatives as catalysts for enantioselective α-sulfenylation of activated C-H bonds in lactones, lactams, and β-dicarbonyl compounds by different electrophilic sulfur reagents is presented. Optically active products are obtained in good to excellent yields and up to 91 % ee. Furthermore, the diastereoselective reduction of α-sulfenylated β-keto esters to give optically active α-sulfenylated β-hydroxy esters has been studied. A model for the intermediate is presented, in which the protonated cinchona alkaloid interacts with the substrate leading to face-shielding in accordance with the enantioselective α-sulfenylation step.
