Reverse-Cope elimination versus 1,3-dipolar cycloaddition in the reaction of enantiopure 2-azetidinone-tethered alkynylaldehydes with N- methylhydroxylamine

Enantiopure 2-azetidinone-tethered alkynylaldehydes 1 react stereoselectively under mild conditions with N-methylhydroxylamine to yield products derived from either intramolecular reverse-Cope elimination or 1,3- dipolar cycloaddition, depending on both t
