Abstract

Chiral imines 1a,b, already synthesized in our laboratory, were converted in good yield by reduction into the corresponding N-benzyl-c-lactams 2a,b. Desilylation followed by oxidation of the hydroxymethyl functionality gave the N-benzyl-b-amino acids 5a,b in good yield and high purity. Starting from compound 6a, the corresponding b-peptoid dimer 8 was prepared, together with its derivatives 9 and 10, these latter displaying conformational restriction about the peptide bond, as evidenced by NMR data.
