Preparation of esters and amides from carboxylic acids and N-formylation of amines promoted by 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-hexachloride (TAPC)
摘要:
A new method is described for the preparation of esters and amides promoted by TAPC from carboxylic acids using a solvent-free grinding technique. The solvent-free N-formylation of amines is also reported. (C) 2013 Elsevier Ltd. All rights reserved.
Water mediated and environmentally friendly, step-wise, tandem & one-pot syntheses of 2-(1H-benzo[d]imidazole-2-yl)-N-arylbenzamide derivatives have been developed by simply combining phthalic anhydride, anilines and phenylenediammonium dihydrogenphosphate. This reaction has an easy workup, provides excellent yields, and uses water as the solvent which is considered to be relatively environmentally benign.

the metal cations present in the enzyme. In agreement with the biological studies, most of the designed compounds have considerable affinity to the active site in comparison with sofosbuvir. Compound 3z with EC50 of 6.0 µM, and an appropriate affinity to the active site could be considered as a new hit for the design of novel HCV inhibitors.
