The synthesis of ω-alkenylallylboronate derivatives is described for the first time. In addition, their performance in the chiral Brønsted acid-catalyzed allylboration/RCM tandem sequence is studied. Cyclic alcohols, displaying the hydroxyl functionality at an exocyclic position and two consecutive stereocenters, are obtained as single diastereoisomers and in high degree of enantioselectivity, in most
首次描述了ω-烯基烯丙基硼酸酯衍生物的合成。此外,还研究了它们在手性布朗斯台德酸催化烯丙基硼化/RCM 串联序列中的性能。在大多数情况下,在环外位置显示羟基官能团和两个连续立体中心的环状醇作为单一非对映异构体和高度对映选择性获得。
