  A one-pot, two step synthesis of 2,2-disubstituted 1-nitroalkenes

  摘要：

  The reactions of ketones 1a-o, nitromethane 2, and a stoichiometric amount of piperidine 3a or ethylenediamine 3b in the presence of mercaptan 6a in THF or CH3CN solution give high yields of beta-nitrosulfides 7a-o. The latter can be oxidized by 8a (m-CPBA or m-CPBA/AcOH) at 0degreesC, 8b (H2O2/AcOH), or 8c (H2O2) at room temperature, thus generating beta-nitroalkylsulfoxides 9a-o, which then undergo elimination to produce medium to high yields of 2,2-disubstituted-1-nitroalkenes 5a-o, when refluxed in a solution of ClCH2CH2Cl (1,2-dichloroethane). After preparation from 1a-o, 2, 3, and 6a, 7a-o were oxidized with 8a, 8b, or 8c in a mixture of CH3CN and ClCH2CH2Cl to generate beta-nitrosulfoxides 9a-o, which then underwent elimination under refluxing under one-pot conditions. Compounds 14 and 15g were also prepared using 13, 2, 3b, and 6, in a similar manner. (C) 2003 Elsevier Science Ltd. All rights reserved.

  An asymmetric intermolecular reaction between enals and nitroalkenes to yield δ-nitroesters has been developed, catalyzed by a novel chiral N-heterocyclic carbene. Key to this work was the development of a catalyst that favors the δ-nitroester pathway over the established Stetter pathway. The reaction proceeds in high stereoselectivity and affords the previously unreported syn diastereomer. We also

  triazolochromenes were formed with complete regioselectivity and new biologically relevant structures were synthesized via extension of the developed procedure and via postfunctionalization. The mechanochemical synthesis was carried out for several salicylaldehydes and gave a clear improvement in the yield of the corresponding triazolochromenes and consequently showed to be a viable alternative for solid salicylaldehydes

  一种新的无金属一锅三组分程序已被开发出来，该程序从市售材料开始，用于完全取代的三唑色烯。水杨醛和硝基烯烃在无溶剂条件下反应，然后以一锅两步顺序将中间体 3-硝基-2H-色烯与有机叠氮化物进行 1,3-偶极环加成。三唑色烯的形成具有完全的区域选择性，并且通过扩展已开发的程序和通过后功能化合成了新的生物学相关结构。对几种水杨醛进行了机械化学合成，并明显提高了相应三唑色烯的产率，因此表明它是固体水杨醛的可行替代品。

  A novel intermolecular cross-double-Michael addition between nitro and carbonyl activated olefins has been developed through Lewis base catalysis. The reaction took place with a large group of beta-alkyl nitroalkenes and alpha,beta-unsaturated ketone/esters, producing an allylic nitro compound in good to excellent yields.
