tert-butyldimethylsilyl (TBS), and triisopropylsilyl (TIPS) acetylenes underwent the Cadiot-Chodkiewicz cross-coupling reaction with different bromoalkynes to form a variety of synthetically useful unsymmetrical diynes in good yields. The diyne alcohol 10 was transformed regio- and stereoselectively into enynes by hydrotelluration, carbometalation, and reduction reactions.
庞大的三烷基甲硅烷基保护的炔烃,例如三乙基甲硅烷基(TES),叔丁基二甲基甲硅烷基(TBS)和三异丙基甲硅烷基(TIPS)乙炔,与不同的溴炔进行了Cadiot-Chodkiewicz交叉偶联反应,以良好的收率形成了各种合成有用的不对称二炔。二炔醇10通过加氢精制,碳金属化和还原反应被区域和立体选择性地转化为烯炔。
