A series of 1,1-dichloro-2,2,3-triarylcyclopropanes (DTACs) was synthesized and evaluated as pure antiestrogens. Addition of 4-methoxy- or 4-(benzyloxy)phenyl Grignard reagents to p-methoxy, p-benzyloxy, or unsubstituted deoxybenzoins, followed by dehydration of the resulting carbinols produced a mixture of E and Z olefins, which were reacted with dichlorocarbene to give O-protected DTACs. The E and
合成了一系列的1,1-二氯-2,2,3-三芳基环丙烷(DTAC),并作为纯抗雌激素进行了评估。将4-甲氧基-或4-(苄氧基)苯基格氏试剂添加到对甲氧基,对苄氧基或未取代的脱氧苯偶姻中,然后将所得甲醇脱水,生成E和Z烯烃的混合物,将其与二氯卡宾反应生成给出O保护的DTAC。通过分步结晶分离E和Z异构体,并去保护中心或双环苯环以提供酚DTAC。用(N,N-二甲基氨基)乙酸乙酯烷基化得到碱性环丙烷。分离出两种氯二芳烃作为DTAC的热解产物,其中一种通过氢解转化为苯酚。在未成熟大鼠子宫胞质溶胶受体测定中,所有DTAC和茚满都是[3H]雌二醇结合的竞争性抑制剂,相对结合亲和力为雌二醇的0.1-3.6%。在3天未成熟小鼠子宫营养试验中,新化合物均未以750微克的剂量产生雌激素作用。在为期3天的未成熟小鼠抗子宫营养试验中,五种带有甲氧基(5a),苄氧基(4d,5c)或(二甲基氨基)乙氧基(7a,7b)中
