-
3β-Hydroxyandrost-4-en-6,17-dione(3-OHAT),a non-androgenic aromatase inhibitor,was synthesized via a new process.With dehydroepiandrosterone acetate as starting material,the synthetic procedure included five steps: epoxidation of C=C bond with performic acid,ring opening of the epoxide with periodic acid,oxidation of 6-hydroxy by IBX,elimination of H2O and hydrolysis of the ester.The total yield was up to 55%.The use of performic acid,an affordable and easily prepared reagent,in epoxidation led to quantitatively the target epoxide.The oxidation of the 1,2-diol by IBX provided the oxidative product with a high yield of 98.5%,moreover,the introduction of IBX avoided the use of chromic reagent,which leads to the tedious work-up for the product purification and environmental pollution.
