This report describes the synthesis of 6alpha,17,21- and 6beta,17,21-trihydroxypregn-4-ene-3,20-dione, 6alpha,7,21- and 6beta,11beta,21-trihydroxypregn-4-ene-3,20-dione, and-for the first time-that of 6alpha,21- and 6beta,21-dihydroxypregn-4-ene-3,11,20-trione. The former four compounds were prepared by 6-hydroxylation of 17,21-trihydroxypregn-4-ene-3,20-dione and 11beta,21-dihydroxypregn-4-ene-3,20-dione
本报告描述了 6alpha,17,21- 和 6beta,17,21-trihydroxypregn-4-ene-3,20-dione、6alpha,7,21- 和 6beta,11beta,21-trihydroxypregn-4-ene-的合成3,20-dione,以及首次出现的 6alpha,21- 和 6beta,21-dihydroxypregn-4-ene-3,11,20-trione。前四种化合物分别通过 17,21-trihydroxypregn-4-ene-3,20-dione 和 11beta,21-dihydroxypregn-4-ene-3,20-dione 的 6-羟基化制备。这是通过后两种类固醇的 3-甲氧基-孕-3,5-二烯的自氧化或用 3-氯过苯甲酸氧化来实现的。6beta-羟基化类固醇的产量,但不是它们相应的6alpha-差向异构体,使用自动氧化比过酸更高。两种
