[reaction: see text] Ruthenium-catalyzed alkyne hydrosilylation or silyl-alkyne Alder ene reactions provide entry into benzyldimethylsilyl (BDMS)-substituted alkenes. The BDMS-vinylsilanes are further elaborated through mild palladium-catalyzed cross coupling and show significant stability to intervening synthetic operations, including silyl ether deprotection.
[反应:见正文]钌催化的炔烃氢化硅烷化或甲硅烷基炔烃Alder烯反应提供了进入苄基二甲基甲硅烷基(BDMS)取代烯烃的入口。BDMS-乙烯基硅烷通过温和的钯催化的交叉偶联进行了进一步的修饰,对介入的合成操作(包括甲硅烷基醚脱保护)表现出显着的稳定性。
