Published in 2020 at "Dyes and Pigments"

DOI: 10.1016/j.dyepig.2019.108062

Abstract: Abstract The solvent-free microwave-assisted one-pot four-component reaction of 1-(2,5-dimethylfuran-3-yl)ethan-1-one, malononitrile, aryl aldehydes and ammonium acetate occurred through a five-step multiple bond-forming transformation (MBFT) to afford 2-amino-4-aryl-6-(2,5-dimethylfuran-3-yl)-pyridine-3-carbonitriles in excellent yields. One of these dimethylfuran tethered 2-aminopyridine-3-carbonitriles… read more here.
