Stereoselective 2,3-sigmatropic rearrangement of the propargyl 2-silylallyl ether(5) leads to the vinyl silane (7), which, after protiodesilylation and palladium catalysed coupling to 3-bromoprop-2-enol, produces the ,-dienynol (10) a key intermediate in leukotriene synthesis.
炔丙基2- silylallyl醚的立体选择性2,3-σ重排(5)通向乙烯基硅烷(7),其protiodesilylation和钯后催化的偶联到3-溴-2-烯醇,产生,-dienynol(10 )白三烯合成中的关键中间体。
