摘要: LDA-mediated cascade carbolithiation reactions of vinylidenecyclopropanes with enones and N-sulfonated imines as well nitroalkene (phenylmethylidene)malononitrile in THF at –78 °C have been realized; the corresponding novel adducts were produced moderate to good yields high diastereoselectivities. The scope limitations are discussed a plausible reaction mechanism based on control experiments performed this work previous literature reports.
