“…Among them, N-heterocycles as typical molecular frameworks of synthetic drugs, natural products, agrochemicals and functional materials, are widely used in organic synthetic chemistry. 1 For example, benzo[4,5]imidazo-[1,2- a ]pyridines are not only a class of significant fluorescent material molecules, 2 but also have potential medicinal properties, such as antidiabetic, 3 anti-cancer, 4–6 anti-malarial, 7,8 antifungal, 9 antischistosomal, 10,11 etc . It is worth noting that benzo[4,5]imidazo[1,2- a ]-pyridines containing a C 1 –N bond have excellent biological activities (Fig.…”
