The 4-substituted silacyclohex-3-enes (3) prepared from the vinyl triflate (9) derived from 1,1-dimethyl-1-silacyclohexan-4-one (1) and higher-order organocuprates provides a versatile template for the construction of non-racemic 3-methyl-4-penten-1-ol (6). Through asymmetric hydroboration, 3 affords the requisite β-hydroxysilane (4) with the ideal geometry to undergo elimination to the chiral acyclic
由衍生自1,1-二甲基-1-silacyclohexan-4-one(1)的三氟甲磺酸乙烯酯(9)和高阶有机铜酸酯制备的4-取代的silacyclohex-3-enes(3)提供了通用的结构模板非外消旋的3-甲基-4-戊烯-1-醇(6)。通过不对称氢硼化,3可获得具有理想几何结构的必需β-羟基硅烷(4),以消除被氧化转化为6的手性无环硅烷(5)。
