Conveniently synthesized novel N-(protected α-tri-, tetra- and pentapeptidoyl)benzotriazoles couple in aqueous aceto-nitrile solution at 0C with free amino acids, dipeptides, and tripeptides- to afford N-terminal-protected polypeptides (61-92%) including those containing unprotected OH, SH, and indole NH groups, with no detectable racemization.
