Epoxy-epimination of cyclic conjugated dienes-VII-
摘要:
[4+2] Cycloaddition of halogenated nitroso benzenes to cyclopentadiene followed by isomerisation of the intermediate adduct occurs already at room temperature to furnish the epoxy-epimine 1 and the epiminopentadienal 2. The structure proof of 1 is based on X-ray analysis.
