Selective Recyclization of 2-Aroylmethyl-1H-benzimidazole Hydrazones by Condensation with Dimethylformamide.-The title hydrazones (III) are converted to the benzimidazoles (V) by reaction with DMF (IV) in the presence of TFA. The mechanism of this recyclization is discussed. -(DZVINCHUK, I. B.; VYPIRAILENKO, A. V.; LOZINSKII, M. O.; Chem.

Thiazine derivatives R 0610Isomerization in the Oxidative Cyclocondensation of 2-Aroylmethyl-1H-benzimidazoles with o-Aminothiophenol. -Oxidative cyclocondensation of the title aroylmethylbenzimidazoles (I) with o-aminothiophenol affords previously unknown benzimidazolyl-2H-benzothiazines (III) or isomeric -4H-benzothiazines (IV) depending on the reaction conditions. Cyclocondensation of p-nitrophenacyl derivative (VII) is complicated by a hydrolytic fission leading to compound (IX). -(DZVINCHUK, I. B.; VYPIRAILENKO, A. V.; LOZINSKII, M. O.; Chem. Heterocycl.
