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).
