Abstract

1,3-Benzoxazines Amines Imines Microwave irradiation One-pot synthesis Triphosgene
Reaction of substituted 2-hydroxyacetophenones with amines under microwave irradiation (M.W.) gave the corresponding imines (Schiff bases) which were treated without separation or identification with triphosgene to give 4-methylene-1,3-benzoxazines in good yields.
