A thiamine hydrochloride (VB1) accelerated, one-pot synthesis of 2-amino-6-(1H-indol-3-yl)-4-arylpyridine-3,5-dicarbonitriles was achieved via four-component reaction of 3-cyanoacetyl indole, aromatic aldehydes, ammonium acetate, and malononitrile in aqueous micellar conditions by a Knoevenagel condensation reaction followed by Michael-addition, which upon cyclization and dehydration yielded the corresponding product in excellent proportion.
