摘要：

A head-to-tail cyclization of a protected linear hexapeptide with a C-terminal O-acyl isopeptide proceeded to give a cyclic O-acyl isopeptide without epimerization. The cyclic O-acyl isopeptide possessed different secondary structures compared with the native cyclic peptide. The isopeptide was then efficiently converted to the desired cyclic peptide via an O-to-N acyl migration reaction using a silica gel-anchored base.
