(III) chloride alters the chemoselectivity of the reaction of the Grignard reagent (1) with ester-acetals and also greatly improves the efficiency of reaction with lactones. In addition it gives improved preparations of the useful intermediates (8), (11) and (12) giving direct access to valuable functionalised allylsilanes of use in annulation reactions.

(111) chloride alters the chemoselectivity of the reaction of trimethylsilylmethyl magnesiumchloride with ester-acetals and also greatly improves the efficiency of reaction with lactones. In addition it gives improved preparations of the useful intermediates (7), (13), (18),(20) and (22) and gives direct access to the valuable functionalised allylsilanes (1) to (3) of use in annulation reactions.
