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. In addition to the well-documented C-2 nucleophilicity, the N nucleophilicity of vinyl azide disclosed in this work opens a new direction for reaction invention involving
whereas others were generated in situ and used for further reaction. They were found to react readily with enol ethers to give nitronic ester, which subsequently were transformed to unsaturated 1,4-dicarbonyl compounds.
