1,3-Dipolar Cycloadditions of Electron-Rich Benzotriazol-1-ylpropenes

Abstract

The preparation of trans-3-benzotriazol-1-yl-1-(N-morpholino)prop-1-ene (1), trans-3-benzotriazol-1-yl-1-ethoxyprop-1-ene (2) and trans-1,3-bis-(benzotriazol-1-yl)propene (3) and their reactions with a benzonitrile oxide (4), N-(2,4-dibromophenyl)-1-phenylnitrilimine (5), and p-nitrophenyl azide (6) are described.
