✦ Synopsis

A Diene Transmissive Diels-Alder Strategy for Oxygenated Nor-Steroid and Triterpenoid Skeletons.

-Swern oxidation of the carbohydrate derived allylic alcohol (II) forms a ketone which cyclizes spontaneously to the diene (III), the stereochemistry of which is controlled by the isopropylidene acetal. A second intermolecular Diels-Alder reaction affords nor-steroid and terpenoid skeletons. -(WOO, SIMON; LEGOUPY,
