Benzo[ a ]phenazines were prepared by condensation of β‐lapachone with 1,2‐phenylenediamine and 4‐chloro‐1,2‐phenylenediamine. The latter diamine gave two regioisomers that could be separated and unambiguously identified by means of their 1 H and 13 C NMR spectra with the aid of 2D NMR experiments, mainly HETCOR and COLOC. © 1998 John Wiley & Sons, Ltd.
