The reaction of cinnamyl chloride witha scrics of alkyl and alkyl aldchydes mediated by tin and aluminium has been shown to be regiosclective and threo diastercosclective. For aldehydes with chirality adjacent to the carbonyl function some diastcrcofacial selectivity is observed. Conjugated aldchyydcs undergo regioselective 1,2-addition to the carbonyl.
