Photocyclisation de N-benzoylenamines. Syntheses de spirocyclohexanes en serie isoquinoleine.
摘要:
Substituted N-benzoylenamines are easily prepared from benzoyl chlorides and cycloalkane carboxaldehydes. Their photocyclization leads, with good yields, to tricyclic spiranic compounds. The regioselectivity of the reaction is studied.

A variety of substitutedspirocyclohexanepiperidines are obtained by the photocyclisation of enamides in which the double bond α to the nitrogen atom is exocyclic to the cyclohexane ring.
