condensations of 1-(2-hydroxyphenyl) pyrroles with a variety of carbonyl compounds are shown to give new 4-substituted-4H-4-methylpyrrolo[2,1-c][1,4]benzoxazines. Some of the products were further functionalized. The ir, uv, and pmr spectra of the title heterocyclic system are discussed. Reaction of 1-(2-hydroxyphenyl) pyrrole with dimethyl acetylenedicarboxylate yielded dimethyl 3-(2-hydroxyanilino) phthalale;
显示1-(2-羟苯基)吡咯与多种羰基化合物的缩合反应产生新的4-取代的-4 H -4-甲基吡咯并[2,1- c ] [1,4]苯并恶嗪。一些产品被进一步功能化。讨论了标题杂环系统的ir,uv和pmr光谱。1-(2-羟基苯基)吡咯与乙炔二羧酸二甲酯反应,生成3-(2-羟基苯胺基)邻苯二甲酸二甲酯。解释结果的机械原理涉及假想的Diels-Alder加合物的重排。
