Condensation of diethyl formylamino- or diethyl acetylaminomalonate with 4-, 5- or 6-nitrogramine 1 afforded the diethyl formylamino- or the diethyl acetylamino[(nitroindol)-3-ylmethyl]malonates 2; reduction of the nitro group followed by N-formylation or acetylation of the resulting amino compounds 3, led to the 4-, 5-and 6-acylamino derivatives 4.
将二乙基甲酰基氨基-或二乙基乙酰氨基丙二酸酯与4-,5-或6-硝基葡糖胺1缩合,得到二乙基甲酰基氨基-或二乙基乙酰氨基[(硝基吲哚)-3-基甲基]丙二酸酯2。还原硝基基团,然后将所得氨基化合物3进行N-甲酰化或乙酰化,从而生成4-,5-和6-酰基氨基衍生物4。
