M. Sekar et al., SYNTHESIS OF NOVEL 3-ACETYL-2-HYDROXY-1-N,N-DIACETYLAMINOCARBAZOLE DERIVATIVES, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 49(5), 1994, pp. 687-690
The synthesis of hitherto unknown 3-acetyl-2-hydroxy-1-N,N-diacetylami
nocarbazole (3a-f), is reported. The hydroxyiminocarbazoles (2a-f), pr
epared from 1-oxo-1,2,3,4-tetrahydrocarbazoles (1a-f) on treatment wit
h acetyl chloride in acetic anhydride yielded the title compounds (3a-
f).
