Water enabled a highly atom- and step-economical, redox-neutral 4-step cascade process, including SNAr/Knoevenagel condensation/[1,5]-hydride transfer cyclization, to construct pharmaceutically important tetrahydroquinoline spiro compounds efficiently.
An environmentally benign cascade redox process was developed for the efficient construction of the pharmaceutically significant spirocyclic tetrahydroquinolines via sequential SNAr/Knoevenagel condensation/[1,5]-hydride transfer/cyclization. This green transformation has the features of being catalyst-free, additive-free, operationally simple, and has high step- and atom-economy.
一种环境友好的级联氧化还原过程被开发用于通过顺序SNAr/Knoevenagel缩合/[1,5]-氢转移/环化高效构建具有药用意义的螺环四氢喹啉。这种绿色转化具有无催化剂、无添加剂、操作简单、步骤和原子经济性高的特点。
