摘要:
A method for organocatalytic, enantioselective Michael addition reactions of thioacetic acid with a range of trans-beta-nitrostyrenes has been developed. The processes, promoted by the chiral amine thiourea organocatalyst, take place in high yields with up to 70% ee. (c) 2006 Elsevier Ltd. All rights reserved.
