  Ring opening of 2-substituted 4-nitrothiophenes with pyrrolidine. Access to new functionalized nitro-unsaturated building blocks

  摘要：

  The reaction conditions of the ring-opening processes of 3-nitrothiophene 7a and of 3-nitrobenzo[b]thiophene 7b with pyrrolidine and silver nitrate were optimized as well as those of the subsequent S-methylation of the ensuing silver enethiolates 8a and 8b to 4-methylthio-2-nitro-1-pyrrolidino-1,3-butadiene 9a and 1-(2-methylthiophenyl)-1-nitro-2-pyrrolidinoethylene 9b. Under such conditions 2-X-substituted 4-nitrothiophenes 7c-i consistently gave good yields of the corresponding 4-methylthio-2-nitro-1-pyrrolidino-4-X-1,3-butadienes 9c-i. The nitroenamine derivatives 9a-i were then reacted with p-tolylmagnesium bromide to furnish moderate to good yields of 4-methylthio-2-nitro-1-(p-tolyl)-4-X-1,3-butadienes 10a,c-i and 1-(2-methylthiophenyl)-1-nitro-2-(p-tolyl)ethylene 10b. Stereochemistry of the interesting building blocks 9a-i and 10a-i was assigned on the grounds of H-1 NMR data and NOE experiments. (C) 2001 Elsevier Science Ltd. All rights reserved.

  取代基对甲苯中反式-2,3-双（芳硫基）-4-硝基-2,3-二氢噻吩β-消除槟榔酚作用机理的动力学研究

  摘要：

  2,3-二氢噻吩衍生物（1b - f）在甲苯中容易进行区域特异性的三丁胺促进的槟榔酚合成消除，从而得到2-（芳硫基）-4-硝基噻吩（2b - f）。对于系列中每个成员显示的相当复杂的动力学行为，基于底物的共轭碱的稳定性提出了合理化建议，该稳定性足以允许沿着反应坐标形成不可忽略的中间离子对浓度。该系统可以得出有关离去基团驱除步骤的直接结论：可以假定在过渡态下碳与离去基团之间键断裂的高级程度。

  日期：——

  The 2,3-dihydrothiophene derivatives (1b–f) readily undergo, in toluene, regiospecific tributylamine-promoted syn-elimination of arenethiol to give the 2-(arylthio)-4-nitrothiophenes (2b–f). For the rather complex kinetic behaviour displayed by each member of the series, a rationalisation is proposed based on a stability of the substrate's conjugate base sufficient to allow formation of non-negligible
