Synthesis of unsymmetrical 3,5-disubstituted 1,2,4-triazole derivatives with their pKa values
(Chiminform Data S A, 2014)
Acylhydrazones (2a-b) were synthesized by the condensation of iminoester hydrochlorides (1a-b) with benzhydrazide. the treatment of acylhydrazones With hydrazine hydrate afforded 4-amino-4H-1,2,4-triazoles. (3a-b). ...
Rapid and efficient synthesis of a new series of 2-aryl-5-fluoro-6(4-phenylpiperazin-1-yl)-1H-benzimidazoles using microwave heating
(Sage Publications Ltd, 2015)
A new series of 2-aryl-5-fluoro-6-(4-phenylpiperazin-1-yl)-1H-benzimidazoles was synthesised from the reaction of 4-fluoro-5-(4-phenylpiperazin-1-yl) benzene-1,2-diamine and iminoester hydrochlorides. 4-Fluoro-5-(4-pheny ...
