ONE-POT SYNTHESES OF 9,10-DIARYL-7H-BENZO[d,e]IMIDAZO[2,1-a]ISOQUINOLIN-7-ONES DERIVATIVES USING AMINO FUNCTIONALIZED NANOPOROUS SILICA SBA-Pr-NH2 AS A SOLID NANO CATALYST

A highly efficient method for the preparation of 9,10-diaryl-7H-benzo[d,e]imidazo[2,1-a]isoquinolin-7- ones derivatives was developed using the green onepotmulticomponent reaction of acenaphthoquinone, benzil and ammonium acetate in the presence of SBA-Pr-NH2 as catalyst which affords the desiredproduct in good yields
