Stereoselective intramolecular axzide 1,3-dpolar cycloaddition

摘要

Ethyl(E)-7-azido-6-[bis(tet-butoxycarbonyl) amino]-2-heptenoate undergoes a stereoselective intramolecular azide 1,3-dipolar cycloaddition leading undergoes a stereoselectiv eintramolecular azide 1,3-dipolar cycloaddition leading to a stable triazoline.The configuration and the conformation of the trizoline obtained were determined by spectroscopic data and confirmed by molecular mechanics calculations.
