A Lewis acid catalyzed intramolecular [3 + 2] cross cycloaddition of cobalt-alkynylcyclopropane 1,1-diesters with carbonyls has been successfully developed. Together with simple and efficient postcycloadditions of the cobalt-alkyne moiety, a general and efficient strategy for construction of structurally complex and diverse medium-sized skeletons and related polycycles was supplied successfully.
一种路易斯酸催化的钴-炔基环丙烷 1,1-二酯与羰基的分子内[3+2]交叉环加成已被成功开发。与钴-炔基部分的简单高效的环加成反应相结合,成功提供了一种构建结构复杂多样的中骨架和相关多环化合物的通用且高效的策略。
