3-Imino-2-amino-isatines were obtained by a one-pot reaction of an excess of aniline (or its derivatives) with 1,2-bis(dimethylamino)-1,2-dichloro-ethene (prepared in situ from DMF). Subsequent hydrolysis yielded the corresponding isatine derivatives in reasonable to high yields. DFT calculations with regard to the mechanisms of this reaction sequence are presented. J.

通过过量的苯胺(或其衍生物)与1,2-双(二甲基氨基)-1,2-二氯乙烯(由DMF原位制备)一锅反应获得3-Imino-2-amino-isatines )。随后的水解以合理的至高的产率产生了相应的isatine衍生物。提出了关于该反应序列机理的DFT计算。J.杂环化学,(2009)。
