The preparation and reactions of 2-benzyloxy-4-benzylideneoxazol-5-one
Abstract
The preparation of the title compound (4) and a survey of its chemistry are described. Its reactivity towards nucleophiles at C-5 is high compared with that of the corresponding 2-phenyl compound (1), and nucleophilic reagents attack (4) exclusively at this position, in contrast to the behaviour of (1).
