Conformationally constrained amino acids: a convenient approach to cis-2,3-methano-GABAs
摘要:
3-Aza-2-oxo-bicyclo[3.1.0]hexanes, which are opened to 2,3-methano-gamma-aminobutyric acids, are obtained in very high yields by a two step procedure from N-protected-N-allyl-alpha-Br-amides. (C) 1999 Elsevier Science Ltd. All rights reserved.
