Abstract

A mixture of isomeric phenyloxazines (2, 3) in a 5:4 ratio was synthesized via a [4 + 2] addition reaction of a heterocyclic diene-precursor prepared from bromoacetophenone oxime and the methyl ester of chrysenequinonecarboxylic acid (1). The structures of the synthesized compounds were confirmed using spectral methods.
