In this report we describe the ultrasound-accelerated synthesis of new naphthoquinone derivatives 6a-f and 7a-c, which possess an aminocarbohydrate chain at the C-2 position of the quinone ring. This novel type of 1,4-naphthoquinone derivative has been synthesized under mild conditions by the reaction of 1,4-naphthoquinone (8a) or methoxylapachol (8b) with different aminocarbohydrates 9a-d. Characterization of all substances was confirmed by one- and two-dimensional nuclear magnetic resonance (NMR) techniques (¹H, 13C-APT, cosy-¹H vs. ¹H and HETCOR ¹J CH) and by high-resolution electrospray ionization mass spectrometry (HR ESI MS).
