栗甾酮A/B环类似物的合成研究 Ⅱ.2β,3β-二羟基-6-胆甾酮的立体选择性合成
STUDIES ON SYNTHESIS OF A/B RING ANALOGUES OF CASTASTERONE Ⅱ.STEREOSELECTIVE SYNTHESIS OF 2β,3β-DIHYDROXY-6-CHOLESTERONE
【摘要】 以胆甾醇为原料,经硝化、还原、消除等反应以及用I2-AgOAc-H2O氧化引进2β,3β-二羟基的方法,立体选择性地合成了具有栗甾酮A/B环结构单元的类似物2β,3β-二羟基-6-胆甾酮。
【Abstract】 2β, 3β-Dihydroxy-6-cholesterone, a structural analogue in A/B rings of castasterone was stereoselectively synthesized from cholesterol via nitration, reduction; elimination and oxidation reactions. The key step in the synthesis is the introduction of 2β, 3β-dihydroxy groups by oxidation with I2-AgOAe-H2O.
