[Cu(bpdo)2.2 H2O]2+–supported SBA-15 n anocataly st catalyze d synthesis of benzoxa nthenone and 2-am ino-chro mene deri vatives efficiently

Xanthenone deriv atives have attracted considerable interest because they possess v arious pharmaceutical ac tivities suc h as anti-bacterial [1], a nti-inflamm atory [2] a nd anti-viral [3] . Also 2-amino-4H -chromene d erivatives are important classes of oxygenated heterocycles [4], which have attracted much interest because of the bi ological activities such as anticoagulant, spasmolytic, diure tic, anti-anaphylactin, anticancer, a nd antidiabetic activities [5].Accordingly in continuation of our prev ious works on synthes is of heterogeneous catalysts and benzoxanthe none and benzopyran c ompounds, here we wa nt to report the synthesis and characterization of [Cu(bpdo)2.2H2O]2+ / SBA-15 used as catalyst for the synthes is of benzo xanthenone and 2-amin o-chromene derivatives by reactio n of aromatic aldehydes,a/B- naphthol, dimed ne or malo nonitrile respectively under solvent-free con ditions with high yield of products moreover a simple experimental a nd work-up procedure without using any hazardous solvents.
