Organocatalytic Stereoselective[8+2]Cycloaddition of Tropones with Azlactones
《CCS Chemistry》2022年第2期650-659,共10页Jinzhao Li Yuhao Mo Liqiao Yan Xiaoming Feng Zhishan Su Xiaohua Liu 
Herein,we report an organocatalytic asymmetric[8+2]higher-order cycloaddition of tropones with azlactones employing bifunctional guanidines as hydrogen-bond-mediated catalysts via a 1,8-addition/annulation process.The...
