Notizen:
The cyclization of the enantiomerically pure α,β-unsaturated ketone 1, an aliphatic aldehyde 3 and ammonia or benzylamine gives diastereoselectively cis-piperidones 4/4′. Although only modest yields were obtained, the presented cyclization has the advantage of being a single step reaction. The products 4 can serve as precursors for all-cis-4-hydroxy-piperidones 5 and novel pipecolic acid derivates 9.
