The reaction of 2‐ N ‐(acetylanilino)‐3‐chloro‐1,4‐naphthoquinone ( 2 ) with bifunctional aromatic amines afforded angular heterocycles 6 and 7 . Reductive acetylation of 7 provided o ‐acyl 9 and O,N ‐diacyl 10 derivatives depending upon the reaction conditions. The ir, uv, pmr and mass spectral data are also presented.
