The A-ring monoglucuronides and monosulfates of 4-hydroxyesteriol were synthesized from 4-hydroxyestriol 16, 17-diacetate by means of the Koenigs-Knorr reaction with methyl α-acetobromoglucuronate and sulfation with sulfur trioxide-pyridine complex, respectively. The conjugated positions of these compounds were unequivocally elucidated by leading the products to guaiacol estrogens. The D-ring monoglucuronides and monosulfates of 4-hydroxyestriol were also obtained from 4-hydroxyestriol 3, 4-dibenzyl ether by glucuronidation and sulfation followed by hydrogenolysis, respectively. The conjugated positions were established on the basis of spectral data of derivatives. The preparation of 4-hydroxyestradiol 17-conjugates is also described.
通过与α-乙酰溴葡萄糖醛酸甲酯的柯尼希斯-克诺尔反应和与三氧化硫-吡啶络合物的硫化反应,分别从 4-羟基雌三醇 16,17-二乙酸酯合成了 4-羟基雌三醇的 A 环单葡糖醛酸酯和单硫酸盐。通过将产物引向愈创木酚雌激素,明确地阐明了这些化合物的共轭位置。通过葡萄糖醛酸化和硫酸化,再通过氢解,还分别从 4-羟基雌三醇 3,4-二苄醚中得到了 4-羟基雌三醇的 D 环单葡萄糖醛酸化物和单硫酸盐。根据衍生物的光谱数据确定了共轭位置。此外,还介绍了 4-羟基雌二醇 17-共轭物的制备方法。
