title: Lewis acids promoted formal intramolecular [3 + 2] parallel and cross-cycloadditions of cyclopropane 1,1-diesters with allenes.
abstract: A novel Lewis acid promoted formal intramolecular [3 + 2] parallel/cross-cycloaddition of cyclopropane 1,1-diesters with allenes has been successfully developed, in which the two C═C of allenes were involved respectively. This provides a general and efficient strategy for the construction of structurally diverse [4.3.0]nonane and [3.2.1]octane skeletons.
