  Rapid Decarboxylative Allylation of Nitroalkanes

  摘要：

  Allyl nitroacetates undergo decarboxylative allylation to provide tertiary nitroalkanes in high yield. Moreover, the transformations are complete within several minutes under ambient conditions. High yields result because aallylation of the intermediate nitronates, which is typically problematic, is reversible under conditions of the decarboxylative allylation process. Lastly, the preparation of substrate allyl nitroacetates by tandem Knoevenagel/ Diels-Alder sequences allows the facile synthesis of relatively complex substrates that undergo diastereoselective decarboxylative allylation.

  日期：1982.1

  study of palladium catalyzed C-allylation of aliphatic nitro compounds is described. Allylic alcohols and/or their acetates and allyl phenyl ethers were employed as allylating agents. The dependence of the reaction yield on nature and quantity of base and structure of the allylic unit is reported and explained. The lowest yield was obtained for allyl alcohol; however it could be considerably increased

  The hydroboration of olefins with Et(2)BH provides diethyl(alkyl)boranes 2 which readily undergo a boron-zinc exchange with Et(2)Zn providing a range of polyfunctional primary, secondary, and benzylic diorganozincs. The resulting diorganozincs 3 have been reacted with various electrophiles (allylic halides, acid chlorides, alkylidenemalonates, ethyl propiolate, nitroolefins) in the presence of CuCN
