A convergent formal [4 + 2] cycloaddition reaction for the construction of structurally appealing spiro-tetrahydroquinolines has been developed, in which, a one-pot reaction is established for the in situ generation of two reagents, a cyclic alkyne and an N-aryliminium ion, from the corresponding precursors in the presence of an Au-catalyst and Brønsted acid, respectively.
已经开发出一种收敛的正式[4 + 2]环加成反应,用于构建结构吸引人的螺-四氢喹啉,其中建立了一个一锅反应,可就地生成两种试剂,环状炔烃和N-芳基亚胺离子,分别在金催化剂和布朗斯台德酸的存在下从相应的前体中分离出来。
