The development and execution of a practical asymmetric synthesis of the estrogenreceptor beta selectiveagonist (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。

The invention relates to a method for synthesising tethered ruthenium catalysts and novel tethered ruthenium catalysts obtainable by this methods. The method involves carrying out an "arene swapping" reaction avoiding the requirement to use complicated techniques making use of unreliable Birch reductions and unstable cyclodienyl intermediates.
