The condensation of isatin with enolisable acyclic and alicylcic 1:3-diketones has been investigated and the structures of the acylated cinchoninic acids obtained have been determined. The condensation of acetonylacetone with potassium isatate is also described. Condensation of isatin with 1:3-cyclohexadiones in neutral or acid media has been shown to give products different from those in alkaline
已经研究了伊斯丁与可固化的无环和水杨酸的1:3-二酮的缩合反应,并确定了所获得的酰化金鸡尼克酸的结构。还描述了丙酮基丙酮与锐钛酸钾的缩合。已经显示,在中性或酸性介质中,靛红与1:3-环己二酮的缩合产生的产物与碱性缩合中的产物不同。
