    摘要:
    描述了将 11-脱氧皮质醇转化为 3α-羟基-5α-化合物的方法。别四氢-11-脱氧皮质醇单乙酸酯(8, 14)是制备别四氢-11-脱氧皮质醇3-或21-葡萄糖醛酸苷的关键中间体,是目标化合物。 5α-二氢-11-脱氧皮质醇21-乙酸酯(4)的制备是通过3-乙氧基-3,5-二烯(2)的氢化,然后酸水解来进行的。当21-四氢吡喃基醚(6)和21-叔丁基二甲基甲硅烷基醚(7)在四氢呋喃中用三仲丁基硼氢化钾在温和条件下处理时,C-3处的羰基发生选择性还原,得到3α-醇(分别为 9 和 10)。然后制备别四氢-11-脱氧皮质醇3-葡糖苷酸(21)和别四氢-11-脱氧皮质醇21-葡糖苷酸(23)。

    Here, we describe the chemical synthesis of the complete sets of 18 novel 3- and 21-monosulfates and their double-conjugated form of tetrahydrocortisol (THF), tetrahydro-11-deoxycortisol (THS), and tetrahydrocortisone (THE) in the 5alpha- and 5beta-series. The principal reactions involved are: (1) selective protection of a specific hydroxy group in substrates; (2) catalytic hydrogenation at C-5 of

  • Biotransformation of corticosteroids by Penicillium decumbens ATCC 10436
    作者:Herbert L. Holland、Doan H. Nguyen、Nicola M. Pearson
    DOI:10.1016/0039-128x(95)00071-w
    日期:1995.9
    The biotransformation of a series of corticosteroids by the fungus Penicillium decumbens ATCC 10436 has been investigated. Conversion to the corresponding 5 alpha-dihydrosteroid was observed for all the Delta(4)-3-ketosteroids studied with the exception of deoxycorticosterone, which was converted to a Delta(1,4)-diene. Deoxycorticosterone acetate was, however, converted to a 5 alpha-dihydro product concomitant with ester hydrolysis. Other substrates carrying a C-21 acetoxy group were also hydrolyzed to the alcohol. In two cases (resulting from deoxycorticosterone acetate and 11-deoxycortisone) the 5 alpha-3-keto product was further reduced to the 3 beta-alcohol. No reduction of Delta(1,4)-dienes was observed.
