Abstract :A series of NH-substituted-1,4-quinones, possessing one, two, three or not chlorine, were synthesized by the reaction between different quinones insert ignore into journalissuearticles values(p-chloranil insert ignore into journalissuearticles values(1);, p-toluquinone insert ignore into journalissuearticles values(2);, or 2,3-dichloro-1,4-naphthoquinone insert ignore into journalissuearticles values(3);); and insert ignore into journalissuearticles values(-);-cis-myrtanylamine insert ignore into journalissuearticles values(5); via nucleophilic reactions. Moreover, 2-bromo-1,4-naphthoquinone insert ignore into journalissuearticles values(4); was reacted with 2-insert ignore into journalissuearticles values(methylthio);ethylamine insert ignore into journalissuearticles values(11); to produce aminosubstituted naphthoquinones insert ignore into journalissuearticles values(12 and 13);, bearing with bromine and not bromine. In addition, 2-bromo-1,4-naphthoquinone insert ignore into journalissuearticles values(4); was reacted with 4′-aminodibenzo-18-crown-6 insert ignore into journalissuearticles values(14); and 4′-aminobenzo-18-crown-6 insert ignore into journalissuearticles values(16); to yield crown-containing 1,4-naphthoquinones insert ignore into journalissuearticles values(15 and 17);, respectively. New compounds were characterized, providing 1H NMR, 13C NMR, FTIR, MS-ESI, UV/Vis and elemental analysis.
