  For the purpose of developing immunoassays of tetrahydro-11-deoxycortisol or its glucuronides, various haptenic derivatives were synthesized. The 3-hemisuccinate (15), 21-hemisuccinate (8), 3-hemiglutarate (16), 21-hemiglutarate (9) and glucuronides (19, 23, 25) of tetrahydro-11-deoxycortisol were prepared starting from 11-deoxycortisol 21-acetate (1). Then, antisera were elicited in two rabbits by immunization with the conjugate of tetrahydro-11-deoxycortisol 3-glucuronide (19) with bovine serum albumin. It was found that the antisera had binding affinities to enzyme-labeled antigens prepared from 15, 16 and 19 ; the binding was inhibited by the glucuronide (19) in the enzyme immunoassay procedure.

  为了开发四氢-11-脱氧皮质醇或其葡萄糖醛酸苷的免疫测定法，合成了各种半抗原衍生物。以11-脱氧皮质醇为原料制备四氢-11-脱氧皮质醇的3-半琥珀酸酯(15)、21-半琥珀酸酯(8)、3-半戊二酸酯(16)、21-半戊二酸酯(9)和葡萄糖醛酸苷(19,23,25) 21-乙酸盐(1)。然后，用四氢-11-脱氧皮质醇3-葡萄糖醛酸苷(19)与牛血清白蛋白的缀合物免疫两只兔子，以产生抗血清。发现该抗血清与15、16和19制备的酶标抗原具有结合亲和力；在酶免疫测定过程中，结合被葡萄糖醛酸苷 (19) 抑制。

  The synthesis of the 3-glucuronides of 11-deoxycortisol metabolites is described. 3α, 17α, 20α-Trihydroxy-5β-pregnan-21-oic acid 3-glucuronide (13) and its 20β-epimer (14) were prepared starting from 5β-dihydro-11-deoxycortisol (1). The 20-acetoxy-21-oic acid methyl esters (7, 8) were the key intermediates. Oxidation of 1 with cupric acetate followed by the intramolecular Cannizzaro reaction gave the 20-epimeric 20-hydroxy-21-acids (5, 6), which, on methylation with diazomethane followed by acetylation, were converted into the acetate-methyl esters (3, 4). Reduction of the carbonyl group at C-3 in 3 and 4 with sodium borohydride gave the desired intermediates. Introduction of the glucuronyl residue at the C-3 position was carried out by means of the Koenigs-Knorr reaction. 20-Epimeric 5β-pregnane-3α, 17α, 20, 21-tetrol 3-glucuronides (26, 27) were also prepared.

  介绍了 11-脱氧皮质醇代谢物 3-葡萄糖醛酸的合成。3α，17α，20α-三羟基-5β-孕甾-21-酸 3-葡萄糖醛酸苷（13）及其 20β-epimer （14）是由 5β-二氢-11-脱氧皮质醇（1）开始制备的。20-acetoxy-21-oic acid methyl esters (7, 8) 是关键的中间体。1 与醋酸铜氧化，然后发生分子内 Cannizzaro 反应，生成 20-epimeric 20-hydroxy-21-acids (5, 6)。用硼氢化钠还原 3 和 4 中 C-3 处的羰基，可得到所需的中间体。通过柯尼希斯-克诺尔（Koenigs-Knorr）反应将葡萄糖醛酸残基引入 C-3 位。还制备出了 20-二聚体 5β-孕甾-3α，17α，20，21-四醇 3-葡萄糖醛酸（26，27）。
