Bioactive naphthoquinone-derived heterocyclic compounds have been prepared. Herein, we describe the semisynthesis of a new phenazine, through modified Hooker's reaction, using lapachol as a precursor. This compound was characterised by 2D NMR spectroscopy methods and X-ray analysis.
Cyclohexanone enamines react with dibenzoyldiimide (IIa) at room temperature leading to a I:1 addition product in almost quantitative yield. This adduct, on mild acidic hydrolysis, gives 2-(N,N'-dibenzoyl)hydrazinccyclohexanone (IVa), identical with that obtained from cyclohexanone and (IIa) at lOOa
