We report the synthesis of macrocycles 1−6 via ring closing metathesis of dienes 7−12. Addition of chlorodicyclohexylborane to thermal and microwave assisted RCM of dienes 8 and 9 markedly improves the yield. The geometric isomers of macrocycles 1−3 and 5 have been assigned using X-ray crystallography and NMR.
我们报告的大环化合物的合成1 - 6经由二烯的闭环复分解7 - 12。向二烯烃8和9的热和微波辅助的RCM中添加氯二环己基硼烷显着提高了产率。大环化合物的几何异构体1 - 3和5已经使用X射线晶体学和NMR分配。
