Intramolecular Schmidt Reaction of Vinyl Azides with Cyclic Ketones

Organic Letters, 2018
Cyclic ketones tethered with a vinyl azide group undergo a Schmidt-hydrolysis sequence to give secondary lactams bearing a ketone side chain. Secondary lactams are obtained in a regioselective manner that is not possible in a conventional Schimdt reaction.

Reactions of vinyl azides and β‐haloalkyl azides with active methylene compounds. Synthesis of 1‐vinyl‐1,2,3‐triazoles

Journal of Heterocyclic Chemistry, 1970
AbstractA general synthetic approach to the yet unknown class of 1‐vinyl‐1,2,3‐triazoles is the condensation of active methylene compounds with vinyl azides or their precursors, the β‐haloalkyl azides, in the presence of an alkoxide. Triazole‐4‐carboxylic acids prepared in this manner are decarboxylated smoothly on heating above their melting point ...

The reaction of vinyl azides with sulfoxonium ylids. Synthesis of n-vinyl triazolines and vinyl aziridines.

Tetrahedron Letters, 1981
Abstract Vinyl azides 1 react with dimethylsulfoxonium ylid 3 at the azide function to produce in high yield 1-vinyl-4,5-unsubstituted-Δ-1, 2 -1,2,3-triazolines 4 . Vacuum flash pyrolysis of 4 furnished N-vinylaziridines 7 without formation of pyrolines.
