摘要

The preparation and properties of 4, 5-diphenyl-4-oxazolin-2-one (Ox) derivatives (1) of amino acids are described and these derivatives evaluated as protected intermediates in peptide synthesis. The Ox group-one of the few protecting groups which mask both hydrogens of a primary amino function-is unreactive undei the usual conditions used to remove protecting groups, but may be cleaved under mild reductive or oxidative ...
