Abstract
An enantiomerically pure (1Z,3E)-sulfinyl diene exhibited a high degre e of facial selectivity (alpha:beta = 16:1) upon complexation to an ir on(0) tricarbonyl fragment, producing a [eta(4)-(1Z)-sulfinyl diene]ir on(0) tricarbonyl complex (2; 80%). The iron(0)-dienal complex derived from 2 can undergo a highly diastereoselective allylation with allylt ri-n-butylstannane and BF3 . Et(2)O (diastereomer ratio 95:5); the abs olute stereochemistry of the homoallylic alcohol product (4) was estab lished by X-ray crystallography.
