  Steroidal silicon side-chain analogs as potential antifertility agents

  摘要：

  A number of silicon-substituted analogues of ethynylestradiol that exhibit modified and enhanced biological activities have been synthesized. Particularly noteworthy are a group of [(trialkylsilyl)ethynyl]estradiol analogues that exhibit high antifertility potency and markedly reduced estrogenic activity. The best compounds synthesized are 17 alpha-[(triethylsilyl)ethynyl]estradiol (5) and 17 alpha-[(tert-butyldimethylsilyl)ethynyl]estradiol (33), which show a separation of antifertility from estrogenic activity in the rat. The results of structure-activity studies indicate a good correlation between the observed biological activities and the calculated van der Waals volumes of the three variable silicon substituents.

  摘要：

  （4-戊烯基）氢硅烷与过渡金属盐催化剂的分子内氢化硅烷化以高收率提供五元和六元闭环产物，其中前者占优势。在基于Harrod-Chalk机理的反应方案中已对此进行了合理化，其中同时涉及到Si-金属键和C-金属键。导致六元环产物的七元中间体显然不如六元中间体有利。但是，使用二羰基二钴八羰基化合物，没有发生闭环，仅观察到了齐聚作用。

  The intramolecular hydrosilylation of (4-pentenyl)hydrosilanes with transition metal salt catalysts afforded five- and six-membered ring-closure products in high yields, with the former predominating. This has been rationalized in terms of a reaction scheme based on the Harrod—Chalk mechanism in which both Si-metal and C-metal bonds were involved. The seven-membered intermediate leading to the six-membered
