	1	Brφnsted acidic ionic liquid catalyzed highly efficient synthesis of chromeno pyrimidinone derivatives and their antimicrobial activity显示文摘A series of 8,9-dihydro-2-(2-oxo-2H-chromen-3-yl)-5-aryl-3/f-chromeno[2,3-(flpyrimidine-4,6(5ff,7//)-diones(5a-j) have been synthesized by the reaction of 2-amino-5,6,7,8-tetrahydro-5-oxo-4-aryl-4#-chromene-3-carbonitrile(4a-j) with couma-rin -3-catboxylic acid under neat conditions employing Br0nsted acidic ionic liquid(4-sulfobutyl)tris(4-sulfophenyl)phosphonium hydrogen sulfate as catalyst.Structures of all the compounds were established on the basis of analytical and spectroscopic data.All the compounds were evaluated for their in vitro antimicrobial activity against different bacterial and fungal strains.
