Recently I am researching about VINYLOGOUS MICHAEL ADDITION; ENANTIOSELECTIVE CONSTRUCTION; STEREOGENIC CENTERS; ALDOL REACTIONS; C-C; BUTYROLACTAM; EFFICIENT; DESYMMETRIZATION; STEREOCENTERS; BUTENOLIDES, Saw an article supported by the CSC foundation (China Scholarship Council). Product Details of 94-41-7. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Song, T; Arseniyadis, S; Cossy, J. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone
The synthesis of chiral unsaturated gamma-lactams is reported featuring a highly enantioselective palladium-catalyzed asymmetric allylic alkylation of alpha,gamma-disubstituted 2-silyloxypyrroles. This method allows a straightforward access to optically active gamma-lactams bearing an alpha-quaternary stereogenic center in high yields (up to 93%), high regioselectivities (up to >20:1), and excellent enantioselectivities (up to 95% ee). To further demonstrate the synthetic utility of the method, the resulting allylated products were converted to various versatile chiral building blocks, such as pyrrolidines and pyrrolidinones.
