- REGIOCONTROLLED SYNTHESIS OF THE ERGOSTEROL B-ISOMERS
-
A novel, regiocontrolled synthesis of the ergosterol B-isomers, (1), (2) and (3) is described, the success of which was realized via the highly regioselective formation of intermediate trienoltriflates, (7), (8) and (9).

- Structure and Chemistry of ?-Allyl Palladium Complexes from Steroids
-
The synthesis and structures of ?-allyl palladium complexes prepared from vitamins D2 and D3 and from ergosterol, 7,8-didehydrocholesterol, and 3-epi-cholesterol are described.The mechanism of palladisation is descussed as well as the transformation of the complexes into conjugated trienes or allylic alcohols.
