A Highly Efficient and Selective Route to Isomeric Cyclic Diazadienes
摘要:
A highly selective Lewis acid-catalyzed ring expansion of methylenecyclopropyl hydrazones to isomeric cyclic diazadienes is reported. In general, good to excellent yields and selectivities were obtained for a broad range of hydrazone derivatives.
