Michael addition of nitroalkanes to dimethyl maleate, in acetonitrile and with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as base affords, directly, polyfunctionalized α,β-unsaturated esters, via elimination of nitrous acid
在乙腈中以1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)为碱,将硝基烷烃迈克尔加成到马来酸二甲酯中,通过消除亚硝酸直接提供多官能化的α,β-不饱和酯
