Citric acid was used as green, non-toxic and reusable catalyst for the preparation of substituted 2, 3- dihydroquinazolin-4(1H)ones in high purity and good yields via one-pot three-component reaction of isatoic anhydride with a variety of aldehydes and primary amines or ammonium acetate in water at 80 °C.
Synthesis of 2,3-dihydroquinazolin-4(1H)-ones via one-pot three-component reaction catalyzed by L-pyrrolidine-2-carboxylic acid-4-hydrogen sulfate (supported on silica gel) as novel and recoverable catalyst

A wide variety of 2,3-dihydroquinazolin- 4(1H)-ones has been prepared via one-pot three-component condensation of isatoic anhydride, aldehydes and primary amines or ammonium acetate in the presence of a catalytic amounts of L-pyrrolidine-2-carboxylic acid-4-hydrogen sulfate (supported on silica gel), as green, non-toxic and reusable catalyst, in water at 80 °C.
