The reaction of 1-diethylamino-3-penten-1-yne and 1-diethylamino-4-methyl-3-penten-1-yne with aromatic bifunctional reagents such as pyrocatechol, o-aminophenol, and o-phenylenediamine give 1,3-benzodioxole, benzoxazole, and benzimidazole derivatives containing an unconjugated unsaturated fragment at the C2 ring position.
