Abstract

Our synthesis of the regulatory oxysterol 24(S),25-epoxycholesterol (1) from stigmasterol has been improved by the discovery that cuprate 2 can be coupled with allylic acetate 3 to give in 73% yield in the key step of the most effecient conversion yet of a C22 intermediate to desmosteryl acetate (4). Efforts to prep. diol 5 from sulfone 6 via Payne rearrangement of epoxide 7 will also be presented. [on SciFinder(R)]
