K3PO4-Promoted Cyclopropanation of Electron-deficient Alkenes with 2-Bromo-1,3-Propanedione Compounds
《Chemical Research in Chinese Universities》2019年第6期1002-1007,共6页CHEN Zhanguo WEN Ting HOU Dan 
Supported by the Natural Science Foundation of Shaanxi Province,China(No.2009JM2001);the Innovation Foundation of Postgraduate Cultivation of Shaanxi Normal University,China(No.2008CXB009).
An easy and efficient method for the synthesis of multisubstituted cyclopropane derivatives from electron-deficicent alkenes with 2-bromo-1,3-propanedione compounds was described.For this method,ethylα-cyanocinnamate...
