N-diethoxythiophosphorylimines 1 and N-diphenylthiophosphinoylimines 2 exhibited good reactivity in the aza-Henry reaction. The corresponding products were obtained in excellent chemical yields under mild conditions. Moreover, the asymmetric version of the N-thiophosphoryl imine 1-based aza-Henry reaction was also realized with ee values up to 87% by employing Takemoto’s thiourea as the catalyst.
在1,1,3,3-四甲基胍(TMG)的存在下,N-二乙氧基硫代膦酰亚胺1和N-二苯硫代膦基酰亚胺2在氮杂-亨利反应中表现出良好的反应性。在温和条件下以优异的化学产率获得了相应的产物。此外,通过采用竹本的硫脲作为催化剂,还实现了基于N-硫代磷酰基亚胺1的不对称形式的氮杂-亨利反应,ee值高达87%。
