摘要:
A rhodium-catalyzed intramolecular [3+2] cycloaddition of 1-allene-vinylcyclopropanes (1-allene-VCPs) to construct cyclopentane-embedded bicyclic structures with quaternary stereocenters at the bridgehead position has been developed with good to excellent yields. In addition, this transformation could also be conducted on a large scale with reduced catalyst loading, which could be useful for further derivatizations and applications.
