A variety of 2,4,6-tri- and 2,4,5,6-tetrasubstituted 4H-1,3-oxazines (7 a-i) were synthesized in excellent yields by the reaction of acetylenes (5) in the presence of aluminum chloride with N-[1-(benzotriazol-1-yl) alkyl]amides 4, themselves readily prepared from benzotriazole (1) with amides (2) and aldehydes (3).
