of aryl α-ketocarboxylic acids with 5-aryl-3-nitroisoxazole-4-carboxylates and substituted dinitrobenzenes under oxidative aqueous conditions to afford N-aryl amides is described. The reaction is suggested to proceed via a radical pathway in which a benzoyl nitroxyl radical, the key intermediate formed from reaction between nitroarene and benzoyl radical from glyoxalic acid, couples with hydroxyl radical

The invention relates generally to the creation and use of cyclic sulfonamide containing derivatives to inhibit the hedgehog signaling pathway and to the use of those compounds for the treatment of hyperproliferative diseases and angiogenesis mediated diseases.
series of new alkyl 1-[N-(2-chloro-5-nitro-phenyl)-benzimidoyl] thioureas 3a–h were prepared from benzamides 1a–c. Benzimidoyl thioureas 3a–e afforded 5-nitro-2-phenyl-benzothiazole 5a–c under basic conditions via thiourea–isothiourea rearrangement and SNAr. A mechanistic rationalization supported by the direct formation of benzothioamide 8 and bis-benzimidoyl sulfide 9 derivatives from the reaction
