This Article describes an enantioselective synthesis of cephalostatin 1. Key steps of this synthesis are a unique methyl group selective allylic oxidation, directed C-Hhydroxylation of a sterol at C12, Au(I)-catalyzed 5-endo-dig cyclization, and a kinetic spiroketalization.

The chromium trioxide oxidation of 3β, 12α-dihydroxy-5α-androstan-17-one diacetate in glacial acetic acid has been examined and one of the main products isolated has proved to be 3β, 5ξ, 12α-trihydroxyandrostan-17-one 3, 12-diacetate. The preparation of enol acetates derived from epimeric 3β, 12-dihydroxy-5α-androstan-17-ones is also described.

Steroids bearing C12 oxidations are widespread in nature, yet only one preparative chemical method addresses this challenge in a low-yielding and not fully understood fashion: Schonecker's Cu-mediated oxidation. This work shines new light onto this powerful C-H oxidation method through mechanistic investigation, optimization, and wider application. Culminating in a scalable, rapid, high-yielding, and operationally simple protocol, this procedure is applied to the first synthesis of several parent polyoxypregnane natural products, representing a gateway to over 100 family members.
