5-甲基-,5-溴-和5-碘靛红与磷酰氯的反应以中等收率得到了相应的2,8-二取代的吲哚[2,1- b ]喹唑啉-6,12-二酮。5,7-二氯异丁烷不能与POCl 3反应。靛红和5-溴靛红与三氯氧磷的等摩尔混合物的治疗3吲哚并,得到[2,1- b ] -喹唑啉-6,12-二酮(色胺),2,8-二dibromoindolo [2,1- b ]喹唑啉-6- ,12-二酮,和两种异构的单溴取代的色胺酮衍生物,其中2-溴异构体占优势。
The numerous bioactivities exhibited by tryptanthrins led chemists to develop synthetic approaches towards this important scaffold. In particular, conversion of isatins into tryptanthrins has been the subject of several studies. In this context, by using iodine and potassium hydroxide at room temperature, we have discovered a simple way to convert isatin and seven of its 5-substituted derivatives (Bu

acetonitrile gave indolo[2,1-b]quinazoline-6,12-dione (tryptanthrin) and its 2,8-dimethyl-, 2,8-dibromo-, and 2,8-diiodo derivatives. Oxidative coupling of 5,7-dichloroisatin with isatin under analogous conditions afforded 2,4-dichloroindolo[2,1-b]quinazoline-6,12-dione, while 1,4-dichloroindolo[2,1-b]quinazoline-6,12-dione and 1,4-dichloro-8-methylindolo[2,1-b]quinazoline-6,12-dione were obtained by
在无水乙腈中用高锰酸钾氧化isatin及其5取代的类似物,得到吲哚[2,1 - b ]喹唑啉-6,12-二酮(色胺酮)及其2,8-二甲基-,2,8-二溴-和2,8-二碘衍生物。在类似条件下,将5,7-二氯靛红与靛红氧化偶联,得到2,4-二氯吲哚[2,1 - b ]喹唑啉-6,12-二酮,而1,4-二氯吲哚[2,1 - b ]喹唑啉-6通过将4,7-二氯靛红与靛红和5-甲基靛红分别氧化偶联,得到1,2,2-二酮和1,4-二氯-8-甲基吲哚并[2,1- b ]喹唑啉-6,12-二酮。
