(3alpha,5beta)-3-(乙酰氧基)孕甾烷-20-酮 | 3α-acetoxy-5β-pregnan-20-one | 1491-77-6 | C23H36O3 | 360.537 |
3α-Acetoxy-5β-cholan-24-oic acid was transformed into 3β-acetoxy-5β-pregnan-20-one by a sequence of reactions that involves inversion o f the configuration at C-3 and degradation of the side chain of the bile acid. The procedure would allow the introduction of a label at C-21 of the final compound.
3α-乙酰氧-5β-胆烷-24-酸通过一系列反应转化为3β-乙酰氧-5β-孕烷-20-酮,这些反应涉及在C-3处的构型反转和胆汁酸侧链的降解。该过程将允许在最终化合物的C-21处引入标记。
