Reaction between isopropyl phenyl ketoxime and acetylene in the KOH–DMSO–n-hexane system (70°C, ∼ 5min), along with known 3,3-dimethyl-2-phenyl-3H-pyrrole (51% yield) and 4,4-dimethyl-5-phenyl-1-vinyl-2-pyrrolidinone (7% yield), affords also unexpected 2-(2-ethynyl-3,3-dimethyl-2-phenyl-1-aziranyl)-4,4-dimethyl-5-phenyl-3,4-dihydro-2H-pyrrole (4% yield).
