An efficient method for asymmetric synthesis of apratoxin E 2 is described in this report. The chiral lactone 8, recycled from the degradation of saponin glycosides, was utilized to prepare the non-peptide fragment 6. In addition to this "from nature to nature" strategy, olefin cross-metathesis (CM) was applied as an alternative approach for the formation of the double bond. Moreover, pentafluorophenyl diphenylphosphinate was found to be an efficient condensation reagent for the macrocyclization.

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