Synthesis and C-alkylation of C-protected β-enamino acid derivatives from oxa- thia- and imidazolines
摘要:
Various heterocycles 3a-h can be readily metallated and condensed with a variety of organic nitriles to afford C-protected beta-enamino acid derivatives 1 (or 2). Procedures for alkylation of compounds 1 to obtain 2 as well as a "one-pot" preparation of 2 from 3 are also described. (C) 1999 Elsevier Science Ltd. All rights reserved.
