Abstract
Starting from achiral TFA-protected glycine crotyl ester (3) the interestin g, suitable protected, enantiomerically pure beta-hydroxy-gamma-amino acid isostatine (7) was synthesized in only four steps. The amino acid obtained can directly be introduced into peptides. (C) 1998 Elsevier Science Ltd. Al l rights reserved.
