, p. 3334 - 3349 (2015/08/03)
A series of 4-aryl/heteroaryl-4H-fused pyrans was synthesized via multicomponent reaction in a microwave synthesizer. All the pyrans were evaluated for in vitro xanthine oxidase inhibition. Structure-activity relationship was also established. Among the s
A facile multi component synthesis of some functionalized chromenes and spiroindole derivatives using DABCO as an efficient catalyst
