Addition of sulfonyl carbanions with or without an electrophilic tether has been shown, under certain conditions, to add to α,β-unsaturated oxazolines in good yields and high de's. When 4-bromobutylsulfonyl carbanions are added to unsaturated oxazo

Cyclobutannulation of the bicyclic lactam with allyldimethyltritylsilane is accomplished in high yield with good diastereoselectivity. The resulting tricyclic system is converted to a enantiomerically pure cyclobutane-fused pyrrolidine.

Chiral 3-alkyl-3-arylpyrrolidines were prepared from the substituted bicyclic lactams. Stereoselectivity in the alkylation of bicyclic lactams was improved by using an alkyl triflate or tosylate as the electrophile.
