[Cu(bpdo)۲.۲ H۲O]۲+–supported SBA-۱۵ n anocataly st catalyze d synthesis of benzoxa nthenone and ۲-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 [۱], a nti-inflamm atory [۲] a nd anti-viral [۳] . Also ۲-amino-۴H -chromene d erivatives are important classes of oxygenated heterocycles [۴], which have attracted much interest because of the bi ological activities such as anticoagulant, spasmolytic, diure tic, anti-anaphylactin, anticancer, a nd antidiabetic activities [۵].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)۲.۲H۲O]۲+ / SBA-۱۵ used as catalyst for the synthes is of benzo xanthenone and ۲-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.
