摘 要:Many biologically active complex natural products (e. g. terpenoids, steroids and alkaloids)possess asymmetric quaternary carbon centers. The construction of these asymmetric carbon cen-ters in enantioselective form has been a stimulating subject for organic chemists. Among the methods reported so far, the reaction of construction of nitroolefinic lactones containing asym-metric quaternary carbon centers seems to be promising, because this type of compounds can
