Enantioselective Intramolecular [2+2+2] Cycloaddition of Dienynes for the Construction of Adjacent Three Chiral Centers
[摘要]:A chiral rhodium catalyst realized the first intramolecular [2+2+2] cycloaddition of yne-ene-enes, and chiral multicyclic cyclohexenes with adjacent three chiral centers were afforded with high to excellent ee.
