N-ACETYLINDOXYL IN THE SYNTHESIS OF NEW CONDENSED HETEROCYCLES

Article abstract of DOI:10.1007/BF00476535

Derivatives of a new heterocyclic system thieno<2',3':5,6>pyrimido<3,4-a>indole, were obtained by the reaction of substituted N,O-diacetylindoxyls with excess N-(2-methyl-3-ethoxycarbonyl-4-thienyl)hydrazine.The reaction of N-acetylindoxyl and 4-hydrazinouracil forms 12-amino-1,3-dioxo-2,4,6-trimethylpyrimido<5',4':5,6>pyrimido<3,4-a>indole.
