A one-pot method for the synthesis of cyclopropane-1,1,2,2-tetracarboxylic derivatives was developed starting from aldehydes and cyanoacetic and 2-bromomalonic esters under heterogeneous conditions (K2CO3/PhMe) in the presence of recoverable phase-transfer catalyst Bun 4NPF6.
开发了一种一步合成环丙烷-1,1,2,2-四羧酸衍生物的方法,该方法以醛、氰基乙酸酯和2-溴马来酸酯为原料,在非均相条件下(K2CO3/PhMe),使用可回收的相转移催化剂Bun 4NPF6。
