Abstract
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
