Diazo carbonyl compounds when catalyzed by dirhodium tetraacetate insert to alylic position. This phenomenon was exploited in cyclic systems 3d5d5g and 10. The reactivity toward allylic insertion is corroborated by the unexpected six-membered ring cyclization in the transformation 5g → 9.
重氮羰基化合物在
四乙酸二
钠催化下插入到烯丙基位置。这种现象在3d 5d 5g和10d循环系统中得到了利用。在转化5g→9中意外的六元环环化证实了对烯丙基插入的反应性。
