Synthesis of enantiopure pyrrolidine and piperidine derivatives via ring closing metathesis

The additions of lithiated allylsulfone carbanion to chiral N-sulfinylimines were found to proceed with good to excellent selectivity. The resulting intermediates 4a-d after transformation to dienylamides 7a-d and 16a-d, were converted to functionalized enantiopure piperidines and pyrrolines, respectively, via ring closing metathesis (RCM).

Asymmetric synthesis of functionalized piperidine derivatives: Synthesis of (S)-anatabine

A short and efficient chiral synthesis of 6-aryl-5-phenylsulfonyl- l,2,5,6-tetrahydropyridines was achieved in moderate yield and with good selectivity. The absolute configurations were assigned by extending the methodology to (S)-anatabine and as well with NMR experiments.
