The synthesis of symmetrically 2,2'-disubstituted butestrols [meso-2,3-bis(4-hydroxyphenyl)butanes] and of 6,6'-disubstituted metabutestrols [meso-2,3-bis(3-hydroxyphenyl)butanes] are described [2,2'-substituents: H (1), OH (2), F (3), Cl (4), Br (5), CH3 (6), and C2H5 (7); 6,6'-substituents: H (8), OH (9), Cl (10), and CH3 (11)]. Compounds 1-11 were obtained by reductive coupling of the corresponding
对称的2,2'-二取代的丁烯脂[间位-2,3-双(4-羟苯基)丁烷]和6,6'-二取代的间丁烯酚[间位-2,3-双(3-羟苯基)丁烷]的合成描述[2,2'-取代基:H(1),OH(2),F(3),Cl(4),Br(5),CH3(6)和C2H5(7);6,6'-取代基:H(8),OH(9),Cl(10)和CH3(11)]。通过将相应的1-苯基乙醇与TiCl3 / LiAlH4还原偶联并分离内消旋非对映异构体来获得化合物1-11。通过竞争性结合测定法,相对于[3 H]雌二醇,测定了测试化合物对小牛子宫雌激素受体的结合亲和力。除9外,所有其他化合物的雌激素相对亲和力(RBA)值都非常高,介于1.0%至29%之间。化合物3和6(RBA值:15和29),以及10和11(1.7和5.2)超过了相应的未取代化合物1和8(12和1.0)。在未成熟小鼠的子宫重量测试中,这些化合物表现出强(3、4、6和7),
