Published in 2019 at "European journal of medicinal chemistry"

DOI: 10.1016/j.ejmech.2019.01.060

Abstract: The series of 2-amino-7-propargyloxy-4H-chromene-3-carbonitriles 5a-t were synthesized from corresponding 2-amino-7-phydroxy-4H-chromene-3-carbonitriles 4a-t and propargyl bromide. Two procedures were used in these syntheses: K2CO3/acetone and NaH/DMF procedures with yields of 65-89% and 80-96%, respectively. 1H-1,2,3-Triazole-tethered 4H-chromene-d-glucose conjugates… read more here.
