activity of four aminocarbonyl group containing 'boomerang'-type ring-closing metathesis catalysts have been studied for ten-membered lactone and compared well with the Grubbs I and II as well as the Hoveyda-Grubbs catalysts. The activity was found to be superior to the above three ring-closing metathesis catalysts and suggesting novel stereoselective total syntheses of herbarumin I and stagonolide A.
已经研究了含有四个氨基羰基的“回旋镖”型闭环复分解催化剂对十元内酯的催化活性,并与 Grubbs I 和 II 以及 Hoveyda-Grubbs 催化剂进行了很好的比较。发现其活性优于上述三种闭环复分解催化剂,并提示了草本素 I 和 stagonolide A 的新型立体选择性全合成。
