To the solution of Isatin 1a (1 mmol) in water (20 ml)at 60 C was added o-phenylenediamine 2 (1 mmol). The resulting mixture was stirred and beta-cyclodextrin(15 mol%) was added to the solution. The reaction progress was monitored using TLC by mixture of Hexane – EtOAc (6/4). The completion of the reactionas indicated by TLC in UV-chamber and vapour iodine chamber. The reaction mixture was cooled to room temperature and mixture was extracted by ethyl acetate(2 30mL) and dried over anhydrous sodium sulfate.Ethyl acetate removed in vacuum and crude product obtained. To recycle beta-cyclodextrin, acetone was added in the aqueous media, beta-cyclodextrin recovered. Pure product (6H-Indolo[2,3-b]quinoxaline3a) was obtained by silica gel column chromatography(Hexane/EtOAc) = (7/3 – 6/4) as solid.
The chemical industry reduces the impact on the environment during synthesis 2058-74-4. I believe this compound will play a more active role in future production and life.
