5-dimethylpyrrole-1-acetic acid derivatives were synthesized. The condensation of acetyl methyl carbinol, ethyl glycinate, and the appropriate acetonitrile yielded ethyl 3-substituted 2-amino-4,5-dimethylpyrrole-1-acetate, which was consequently hydrolyzed to produce the corresponding carboxylic acid. The acetamide and trifluoroacetamide series were synthesized by reacting the ethyl 2-aminopyrrole-1-acetates
合成了一系列3-取代的2-氨基-4,5-二甲基吡咯-1-乙酸衍生物。乙酰基甲基甲醇,甘氨酸乙酯和适当的乙腈的缩合产生3-取代的2-氨基-4,5-二甲基吡咯-1-乙酸乙酯,其随后被水解以产生相应的羧酸。通过使2-氨基吡咯-1-乙酸乙酯与乙酸氯或三氟乙酸酐反应合成乙酰胺和三氟乙酰胺系列。通过乙酯的碱性水解形成相应的2-乙酰氨基吡咯-1-乙酸。
