Molybdenum carbene 6 catalyzed ring closing metathesis of (alkenyl)silyl ethers of homochiral allylic alcohols to afford 1,2-oxasilines which were elaborated in situ to give (E)-4-alkyl-1,2-disubstituted 3-buten-1-ol and (Z)-4-alkyl-4-silyl-1,2-disubstituted 3-buten-1-ol derivatives as single geometric isomers.
卡宾6钼催化同手性烯丙基醇的(烯基)甲硅烷基醚的闭环复分解反应,得到1,2-氧杂lines啉,将其原位合成,得到(E)-4-烷基-1,2-二取代的3-丁烯-1-醇和(Z)-4-烷基-4-甲硅烷基-1,2-二取代的3-丁烯-1-醇衍生物为单一几何异构体。
