What is Chemie der Ginkgolide, IV. Herstellung von Ginkgolid B aus Ginkgolid C about?
Chemistry of Ginkgolides, IV^1)^. – Synthesis of Ginkgolide B from Ginkgolide C The reaction of ginkgolide C (3) with tert‐butylchlorodiphenylsilane results exclusively in the formation of the 1‐O‐tert‐butyldiphenylsilyl ether 5, which when treated with O‐phenylchlorothioformate leads to the 7‐phenyloxythiocarbonyl derivative 6. The reduction of 6 with tributyltin hydride/AIBN yields the 1‐O‐tert‐butyldiphenylsilyl ether 7 of ginkgolide B (2). Removal of the silyl protective group with tetrabutylammonium fluoride gives pure ginkgolide B (2). The structures of the reaction products were confirmed by analytical and spectroscopic methods.
