The successful application of the nickel catalyzed, intramolecular [4+4] cycloaddition of bisdienes to the preparation of both the AB and BC ring systems of the taxane diterpenes is described. This cycloaddition methodology provides the basis for a general and efficient route to angularly alkyl-subs

Hydroxypicrasan-3-one, a compound having the correct relative stereochemistry of al1 the six ring-juncture chira1 centers of the picrasane skeleton, was synthesized from a known tricyclic compound, using the orthoester Claisen rearrangement and lead tetraacetate oxidation as key reactions.

A novel and general approach has been delineated lor the enantiomerically pure synthesis of the angularly fused tricyclic system of the pentalenolactone family of compounds. D-Glucose is used as starting material and a diasteroselective Diels-Alder reaction sets the elements for the ring junctions.

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.
