A direct and single-step method has been developed for the synthesis of mono and 2,3-disubstituted quinoxalines by using a AlCl(3) induced (hetero)arylation of 2,3-dichloroquinoxaline. Both symmetrical and unsymmetrical 2,3-disubstituted quinoxalines can be prepared conveniently by using this method under appropriate

The reaction of o-phenylene diamine and ethyl oxamate is reinvestigated and led to 3-aminoquinoxalin-2(1H)-one rather than benzimidazole-2-carboxamide as was previously reported. The structure of the obtained quinoxaline has been confirmed by X-ray. The anti-tumor activity of synthesized quinoxalines 1-21 has

Treatment of 6-aminothiouracil (1) with 2,3-dichloroquinoxaline (2) in ethanol/TEA afforded 6-amino-2-(3-chloroquinoxalin-2-ylthio)pyrimidin-4(3H)-one (3), which was refluxed in DMF to give 2-aminopyrimido[2',1':2,3]thiazolo[4,5-b]quinoxaline-4-one (4). Compound 4 was utilized as a key intermediate for the synthesis of a new pyrimido[2',1':2,3]thiazolo[4,5-b]quinoxaline derivatives 5-14via the reaction

Some heterocyclic systems namely cholest-5-en-7-thiazolo[4,5-b]quinoxaline-2-yl-hydrazone] were synthesized by the reaction of cholest-5-en-7-one-thiosemicarbazone with 2,3-dichloroquinoxaline at 80 degrees C in high yield. The thiosemicarbazone derivatives were obtained by the condensation of the thiosemicarbazide with steroidal ketones. All the compounds have been
