on oxidation give 3-alkylprop-1-en-3-ols in good yields. The reaction works for primary, secondary, benzylic, and even tertiary alkylboronic esters, providing allylic alcohols bearing almost any alkyl group available using organoborane chemistry and incorporating all features of such groups.
试剂3-氯-1-硫代丙烯( 4 )可以通过用t -BuLi处理1-溴-3-氯丙烯来产生。它是不稳定的,但如果在烷基硼酸酯(例如3 )存在下在低温下生成,则会原位捕获重排产物2,其在氧化时以良好的产率得到 3-烷基丙-1-烯-3-醇。该反应适用于伯、仲、苄基甚至叔烷基硼酸酯,提供带有几乎任何使用有机硼烷化学可获得的烷基并结合这些基团的所有特征的烯丙醇。
