Attempts to evolve a new peptide synthesis using boron reagents have led to several new amide syntheses, involving either trialkylboranes. trialkoxyboranes, chlorodialkoxyboranes or dialkoxyboranes. The method using the readily available trimethoxyborane may be of general synthetic value. A new peptide synthesis was realized that gave a product of high optical purity but the low conversions achieved do not make this approach of value, in ...
