The methylation of 2-formyl-3-hydroxyindole was studied, and the sequence of introduction the methyl groups was traced by1H NMR spectroscopy. The O-methyl, N-methyl, and N,O-methyl derivatives of 2-formylindole, and also the O-methyl and N-methyl derivatives of 2-methyl-3-ethoxycarbonyl-4-hydroxypyrrole were synthesized. Novel derivatives of indolyl- and pyrrolylacrylic acids were obtained on the basis
研究了2-甲酰基-3-羟基吲哚的甲基化反应,并通过1H NMR谱追踪了甲基的引入顺序。合成了2-甲酰基吲哚的O-甲基、N-甲基和N,O-甲基衍生物,以及2-甲基-3-乙氧基羰基-4-羟基吡咯的O-甲基和N-甲基衍生物。在吲哚和吡咯系列的一些 O-和 N,O-取代醛的基础上,获得了吲哚基丙烯酸和吡咯基丙烯酸的新型衍生物。
