β¦ Synopsis
ANtZSCt:
A highly reqioseZectrive redu&ioz~ of epoxy allylic alcohols to chiral butmiienyf alcohols and its application to tax01 skeleton is descxibed.
Antitumour taxoids have always been a constant challenge to organic chemists.
Among these classes of natural products, taxol' (1) occupies the prominent position not only because of its biological significance, 2 but also its structural complexities.

The transformation of partially protected aldofuranoses into dienes by Wittig olefination of the anomeric center followed by either allylation or oxopalladation of alkoxy-l,2-propadienes is described. Ring-closing metathesis of the linear dienes gives rise to a variety of highly functionalized and c
