Stable allylboronates with a stereogenic centre α to the boronic ester moiety represent versatile reagents for stereoselective synthesis of homoallylic alcohols. Use of microwave irradiation in desilylation and sigmatropic rearrangement reactions allows rapid synthesis of α-chiral allylboronates utilized in the highly diastereo- and enantioselective synthesis of (Z)-configured homoallylic α-hydroxy
在硼酸酯部分上具有立体异构中心α的稳定的烯丙基硼酸酯代表用于立体选择性合成均烯丙基醇的通用试剂。通过在甲硅烷基化和σ重排反应中使用微波辐射,可以通过向乙醛酸乙酯中加成烯丙基来快速合成(Z)-构型均烯丙基α-羟基酯的高度非对映和对映选择性合成中使用的α-手性烯丙基硼酸酯。
