Bismuth nitrate catalyzed condensation reactions of indoline with 1,2‐ and 1,3‐diketones were investigated and were reported to proceed via different reaction pathways with the involvement of one or two of the carbonyl groups. While the reaction of indoline with cyclohexane‐1,3‐dione (4) gave solely condensation product, the reaction between the acetylacetone (5) and indoline provided N‐acetyl indoline
研究了硝酸铋催化的吲哚啉与1,2-和1,3-二酮的缩合反应,据报道该反应通过不同的反应途径进行,其中涉及一个或两个羰基。吲哚啉与环己烷-1,3-二酮(4)的反应仅产生缩合产物,而乙酰丙酮(5)与吲哚啉之间的反应则提供了N-乙酰吲哚作为逆醛醇缩合工艺的单一产物。与1,3-二酮相反,与苯甲腈(17)的反应在困难的条件下进行,并得到副产物。
