Bis(methoxycarbonyl)carbene, generated by the copper(II)-catalyzed fragmentation of 2,5-dichlorothiophenium-1-bis(methoxycarbonyl) methylide (3) undergoes rapid and efficient insertion into the N-H bonds of primary and secondary amines to generate N-substituted aminomalonic esters in good to excellent yields.
双(甲氧基羰基)卡宾由铜(II)催化的2,5-二氯噻吩鎓-1-双(甲氧基羰基)甲基化物(3)裂解生成,可快速有效地插入伯胺和仲胺的N-H键中,生成N -取代的氨基丙二酸酯具有良好至极好的产率。
