Abstract

A multistep approach to construct thiazole-derived aminobenzimidazoles from commercially available amino acids, amines, carboxylic acids, and α-halo ketones is described. Coupling of 9-fluorenylmethoxycarbonyl-protected (Fmoc-protected) amino acids to resin-bound aminobenzimidazoles provides essential intermediates for the construction of an array of thiazoles by utilizing the Hantzsch cyclization strategy. The aminobenzimidazole-tethered thiazoles were isolated in moderate yields.
