  摘要：

  通过在室温下通过sp 3 C-N键裂解，开发了一种前所未有的亚磺酸与磺酰胺的无催化剂烷基化反应。在没有外部催化剂和添加剂的情况下，各种各样的N-苄基和N-烯丙基磺酰胺与亚磺酸偶联，以中等至极好的收率得到结构多样化的砜。此外，N-（2-酰基）烯丙基磺酰胺与亚磺酸的反应提供了具有独有的Z选择性的三取代烯丙基砜的便利途径。

  Highly Efficient aza-Baylis−Hillman Reaction of N-Tosylated Imines with MVK, Acrolein, and Phenyl Acrylate or α-Naphthyl Acrylate:  Lewis Base Effects and A Convenient Method to Synthesize α,β-Unsaturated β-Amino Carbonyl Compounds

  摘要：

  This paper describes several highly efficient aza-Baylis-Hillman reactions of N-tosylated imines with MVK, acrolein, and phenyl acrylate or alpha-naphthyl acrylate in the presence of a Lewis base. In most cases, the reaction can be completed within 1 h using the appropriate Lewis base catalyst. An efficient method to synthesize beta-amino ketones, aldehydes and esters in high yields and short reaction time has been developed.

• The aza-Morita–Baylis–Hillman reaction of electronically and sterically deactivated substrates

  The aza-Morita–Baylis–Hillman (azaMBH) reaction has been studied for electronically and sterically deactivated Michael acceptors. It is found that electronically deactivated systems can be converted with electron-rich phosphanes and pyridines as catalysts equally well. For sterically deactivated systems clearly better catalytic turnover can be achieved with pyridine catalysts. This is in accordance with the calculated affinities of the catalysts towards different Michael-acceptors.

  aza-Morita-Baylis-Hillman (azaMBH) 反应已经针对电子和立体位阻去活化的Michael受体进行了研究。研究发现，电子去活化的系统可以通过使用富电子的膦和吡啶作为催化剂同样良好地进行转换。对于立体位阻去活化的系统，使用吡啶催化剂可以更明显地提高催化转化率。这与催化剂对不同Michael受体的计算亲和力相符合。

  In the Baylis-Hillman reaction of N-benzylidene-4-methylbenzenesulfonamide with methyl vinyl ketone (MVK), we found that, in the presence of a catlytic amount of DMAP, PPh^3 or DABCO as Lewis base, jthe Baylis-Hillman reaction can be greatly accelerated to give the normmal Baylis-Hillman adducts 1 in good or jvery jhigh yields. However, with Pbu^3 as a Lewis base, the abnormal Baylis-Hillman adducts

  在N-亚苄基-4-甲基苯磺酰胺与甲基乙烯基酮(MVK)的Baylis-Hillman反应中，我们发现，在催化量的DMAP、PPh^3或DABCO作为路易斯碱存在下，Baylis-Hillman反应可以大大加速以提供正常的 Baylis-Hillman 加合物 1 的良好或非常高的产量。然而，以Pbu^3为路易斯碱，在相同的反应条件下形成了异常的Baylis-Hillman加合物2和3。还检查了取代基的影响并提出了合理的反应机制。

  The aza‐Morita‐Baylis–Hillman (aza‐MBH) reaction has been studied in a variety of solvents, a selection of imine substrates and with various combinations of PPh3 and para‐nitrophenol as the catalyst system. The measured kinetic data indicates that the effects of solvent and protic co‐catalyst are strongly interdependent. These results are most easily reconciled with a mechanistic model involving the

  已在多种溶剂，多种亚胺底物以及PPh 3和对硝基苯酚的各种组合作为催化剂体系中研究了aza-Morita-Baylis-Hillman（aza-MBH）反应。测得的动力学数据表明，溶剂和质子助催化剂的作用密切相关。这些结果最容易与涉及两性离子中间体在催化循环中可逆质子化的机理模型相吻合，这也得到31 P NMR光谱学和量子化学研究的支持。

It was found that in the presence of acidic additives the reaction rate could be accelerated to give aza-MBH adducts in good to excellent
