Domino Synthesis of 2-Substituted Benzothiazoles by Base-Promoted Intramolecular C-S Bond Formation

A new, transition-metal-free, domino synthesis of 2-substituted benzothiazoles has been developed, involving base-promoted one-pot addition of active methylene compounds to o-iodoarylisothioacyanates and subsequent intramolecular C-S bond formation of the

Synthesis of 4-amino-3-cyano-2-methylsulfanyl-1 H-[1,5]benzodiazepine, benzo[1,3]azole, and pyrazolobenzo[1,3]azole derivatives via a new utility of bis(methylsulfanyl)methylene derivatives

Novel polysubstituted 1,5-benzodiazepine 5, 2,2-bis(methylthio)benzoxazoles 8a-d, 2,2-bis-(acetyl)benzoxazole 8e, 2-(3-methyl-1-phenylpyrazolo4-yl) benzoazole derivatives 16a-c, as well as the previously reported 2-di[cyano(acetyl)-methylene]benzothiazole

SYNTHESIS OF SOME NEW FUSED HETEROCYCLES CONTAINING A BRIDGEHEAD NITROGEN ATOM UNDER PTC CONDITIONS. A NEW APPLICATION OF CYANOKETENE S,S-ACETALS

A novel synthesis of some fused heterocyclic compounds containing a bridgehead nitrogen atom was achieved using PTC conditions.Suitable ketene S,S-acetals were thus prepared and allowed to react with some o-substituted anilines to give (2,3-dihydrobenzothiazol-2-ylidenyl)malonodinitrile, 2a, ethyl (2,3-dihydrobenzothiazol-2-ylidenyl)cyanoacetate, 2b, (2,3-dihydrobenzoxazol-2-ylidenyl)malonodinitrile, 2c, ethyl (2,3-dihydrobenzoxazol-2-ylidenyl)cyanoacetate, 2d, (2,3-dihydrobenzimidazol-2-ylidenyl)malonodinitrile, 2e, and ethyl (2,3-dihydrobenzimidazol-2-ylidenyl)cyanoacetate, 2f.These afforded the desired products on reaction with a variety of halo compounds.
