Opening of the Furandione Ring with o-Aminothiophenol: Synthesis of 2H-1,4-Benzothiazine-2,3(4H)-dione

5-Aryl-4-(3-arylquinoxalin-2-yl)furan-2,3-diones react with o-aminothiophenol to form 2H-1,4-benzothiazin-2,3-(4H)-dione and (2Z)-1-aryl-2-[3-arylquinoxalin-2(1H)-ylidene]ethan-1-ones.

A new route to construct 1,2-dihydroquinoxaline and 1,4-benzoxazine derivatives stereoselectively and its application to novel pyrazolo[1,5-α] quinoxaline oxides

1,2-Dihydroquinoxaline and 1,4-benzoxazine skeletons were constructed stereoselectively from easily available aryl methyl ketones via a two-step procedure in mild conditions with high yields. Moreover, the application of this reaction provided a convenien

Efficient synthesis of dialkyl (2Z)-2-[(E)-1-aryl-2-(3-arylquinoxalin-2-yl) ethenyl]but-2-enedioates

The reaction of dialkyl acetylenedicarboxylates 4 with 1-aryl-2-[(3- arylquinoxalin-2(1H)-ylidene)-ethanones 3 in the presence of Ph3P leads to dialkyl (2Z)-2-[(E)-1-aryl-2-(3-arylquinoxalin-2-yl)ethenyl]-but-2- enedioates 1 in good yields.
