Abstract

Conceptually, the [2, 3]-Witting rearrangement'of bis-allylic ethers is a convenient, general vehicle to 1, 5-dien-3-ols which are valuable as substrates for the oxy-Cope rearrangement.* In order to establish the feasibility of such an approach within unsymmetrical frameworks, however, many questions must be elucidated which remain largely~ nexplored.~-~ There are positional ambiguities at both the migrating termini in terms of the possibilities for [2, 3] ...
