Biomimetic Synthesis of Chaxine and its Related Compounds
The highly oxidized natural products chaxine B and BB have been synthesized from ergosterol in eight steps according to a route inspired by their proposed biosynthesis; key steps were an oxidative cascade from a furan intermediate to an enol ester using m-chloroperbenzoic acids (MCPBA), followed by diastereoselective epoxidation and acyloxy migration. This concise synthesis resulted in the revision of the structures of chaxine B and its naturally occurring analogs and syntheses of the unnatural analogues of these natural products for biological investigations.

Biomimetic Synthesis and Structural Revision of Chaxine B and Its Analogues
Chaxine B and its analogues were synthesized from ergosterol in eight steps on the basis of our proposed biosynthetic pathway, which includes a highly site-selective and regioselective Baeyer-Villiger oxidation as the key step. This synthesis enabled the revision of the structures of chaxine B and its analogues.
