Four new sigmatropic sequences triggered by the regiocontrolled -Wittig rearrangement of unsymmetrical bis-allylic ethers (1) to the 1,5-dien-3-ols (2) are described, which provide unique, regiocontrolled methods for the synthesis of a wide variety of unsaturated carbonyl compounds possessing interesting molecular frameworks.The newly developed sequences include the -Wittig-Claisen, the tandem -Wittig-oxy-Cope, the tandem oxy-Cope-Claisen, and the tandem oxy-Cope-Cope sequences.

Compounds of the formula (I) wherein R2 is a branched or unbranched, saturated or ethylenically mono or di unsaturated aliphatic radical, Z is —CH2OH, —CH2OAc or —CHO, m is a whole positive integer of one or more, and Ac is an acetyl group are synthesized by a process wherein a 1-alken-3-yl alkylate, is reacted with a halo alkanol Grignard reagent.
