A general synthesis of 6-azaoxindoles, substituted in the 3- and 5-position, has been developed starting from 4-methoxycarbomethyl-3-nitropyridine, via hydrogenation of the nitro group and cyclisation of the resulting 3-amino-4-methoxycarbomethyl-pyridine.
由4-甲氧基碳甲基-3-硝基吡啶开始,通过硝基的氢化和环化所得的3-氨基-4-甲氧基碳甲基-,已经开发了在3-和5-位被取代的6-氮杂肟基的一般合成。吡啶。
