A series of alkyl derivatives of plumbagin (2-methyl-5-hydroxy-1,4-naphthoquinone), analogous to Vitamin K, have been synthesized. Plumbagin reacts with carboxylic acid in presence of silver nitrate and ammonium peroxydisulphate to form its alkyl derivatives. The compounds synthesized were characterized by MS, IR, 1 H and 13C-NMR Spectroscopy. The derivatives prepared may find application as antithrombotic agents and may facilitate designing of similar newer analogues.

In the 13C NMR spectrum of ] -aminopyrene (1) in [D6] acetone all carbon atoms are anisochronous. Most of the sixteen signals can be safely assigned by selective 13C{1H}double resonance experiments and by the interpretation of proton-coupled 13C as well as with the aid of off-resonance noise-decoupled 13C{1H} spectra. Substituent effects on chemical shifts in rings A, B, and D are compared with those of the 1- and 2-aminonaphthalenes (2, 3). Even in ring C, most distant from the substituent, relatively strong high-field shifts are observed which are ascribed to mesomerism.
