A copper catalyzed enantioselective[3+2]annulation of donor-acceptor cyclopropanes with cyclic ke-tones has been developed,providing a concise protocol to enantioenriched 1-oxaspiro[4.5]decanes in up to 98% yield with up to >99/1 dr and up to 92%ee.In addition,this method also provides a facile access to the enantioselective desymmetrisation of various 4-substituted cyclohexanones.The resulting products were easily converted to the core structures of two natural products Heliespirones A and halogenated sesquiterpene isolated from L.saitoi.
