Abstract
N-Protected LL-dipeptide alcohols 3a-p, diastereomeric mixture (3d + 3d') and tripeptide alcohols 6a-c were synthesized by treatment of various amino alcohols with N-protected(alpha-aminoacyl)benzotriazoles 1a-c, 1f-m, (1a + 1a') and N-protected(alpha-dipeptidoyl) benzotriazoles 5a, 5b respectively in good yields with complete retention of chirality.
