A convenient one-potthree-componentsynthesis of indeno[1,2-b]pyrrol-4(1H)-ones has been developed. The reaction of ninhydrin, 1,3-dicarbonyl compounds, and primary amines in the presence of PPh3 in MeCN at room temperature produces the respective indeno-[1,2-b]pyrrol-4(1H)-ones in high yields. The synthesized pyrrole derivatives have been used in the Diels–Alder reaction with dialkyl acetylenedicarboxylates
已经开发了方便的一锅三组分合成茚并[1,2 - b ]吡咯-4(1H)-一。茚三酮,1,3-二羰基化合物和伯胺在PPh 3的存在下于室温下在MeCN中反应生成高产率的相应的茚并[[1,2- b ]吡咯-4(1 H)- 。合成的吡咯衍生物已与MeCN中的乙炔二羧酸二烷基酯在回流条件下用于Diels-Alder反应,以高收率获得茚并[1,2- b ]吡喃并[3,4- d ]吡咯。
