The development and execution of a practical asymmetric synthesis of the estrogen receptor beta selective agonist (8R,10aS)-6-(trifluoromethyl)-8,9,10,11-tetrahydro-8,10a-methanocyclohepta[1,2]indeno[4,5-d][1,2,3]triazol-7(3H)-one is described. The optimized route features a key chiral auxiliary-mediated dialkylation approach to set the all-carbon quaternary center with exceptional stereocontrol. Overall
雌激素受体β选择性激动剂(8 R,10a S)-6-(三氟甲基)-8,9,10,11-四氢-8,10a-甲亚甲基环庚烷的实用不对称合成[1,2]的开发和执行[1,2]描述了茚并[4,5- d ] [1,2,3]三唑-7(3 H)-one。优化的路线采用了关键的手性辅助介导的二烷基化方法,以使全碳四元中心具有出色的立体控制能力。总体而言,该化学方法已用于通过13个最长的线性步骤以大于99%的ee制备21%的总收率的> 30 kg候选药物。
