Intramolecular ene reactions of allenylsilanes can be effected with a variety of imines, aldehydes and alkenes as enophiles, forming five and six membered rings. These reactions are cis stereoselective in all cases studied, and appear to proceed via a concerted, pericyclic process. The cycloadditions all generally occur under mild thermal conditions and some involving imino enophiles can also be effected at lower temperatures using Lewis acid catalysis.

Allenic zinc reagents (R1R2C=C=C(R3)ZnL) are efficiently prepared by the reaction of propargylic substrates (R1R2C(X)C≡CH, X = MeSO2O,Cl, R2NCO2) with a variety of tri
