Abstract

A variety of N-carbobenzoxy, N′-formyl gem-diaminoalkyl derivatives have been obtained through Goldsmith-Wick reaction of Z-α-amino acid/peptide acid derived isocyanates with 96% HCOOH in presence of 4-dimethylaminopyridine (DMAP) as catalyst. The reaction proceeds to completion within 2–4 h and results in good yields of the products isolated as stable solids.
