A chiral five-membered, silyl enol ether containing, steroidringD precursor has been synthesized from carvone. This silyl enol ether has been applied in the synthesis of a chiral C17 functionalized steroid skeleton using the addition of a carbocation, generated with ZnBr2 from a Torgov reagent, followed by cyclization of the adduct by treatment with acid.
