supporting information; experimental part, p. 4444 - 4447 (2009/12/25)

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(α-aminoacyl)benzotriazoles 1a-c, 1f-m, (1a + 1a′) and N-protected(α-dipeptidoyl)benzotriazoles 5a, 5b respectively in good yields with complete retention of chirality.
