Abstract: Abstract In this paper, five novel 1,4-naphthoquinone N-aroylthiourea derivatives were synthesized, by the reaction of 2,3-diaminonaphthalene-1,4-dione and aroylisothiocyanates, in excellent yield (88–96%) and characterized by using FT-IR, 1H/13C NMR and HRMS. In addition, the molecular… read more here.

Abstract: Abstract A facile and efficient synthesis of novel naphthoquinone-based chalcone hybrids (7 and 24) via the microwave-assisted one-pot three-component reactions of 2-substituted-1,4-naphthoquinones, N,N-dimethylformamide dimethyl acetal (DMF-DMA), and acetophenone derivatives has been reported. Whereas the synthesis… read more here.
