In this paper, we presented a novel strategy to control ROP of -amino acid N-carboxy-anhydrides using the concept of frustrated Lewis pairs (FLPs). An FLP intermediate containing an interaction between the bulky borane Lewisacid and the amine groups of the propagation chain end is essential to accomplish the polypeptide synthesis with well-defined structures under mild conditions.
