A concise enantioselective synthesis of l-(−)-733,061 and (2S,3S)-methyl 3-aminopiperidine-2-carboxylate using catalytic enantioselective aza-Henry reaction as key step
摘要:
An efficient enantioselective synthesis of L-(-)-733,061 and (2S,3S)-methyl 3-aminopiperidine-2-carboxylate is accomplished by means of catalytic enantioselective aza-Henry reaction. A key feature of this protocol is organocatalysis as genesis of chirality to ensure high degree of distereo- and enantiocontrol. (C) 2011 Elsevier Ltd. All rights reserved.
