N,N,N',N' ‐tetrabromobenzene‐1,3‐disulfonamide and poly( N , N ’‐dibromo‐ N ‐ethyl‐benzene‐1,3‐disulfonamide) were used as efficient catalysts for one‐pot synthesis of new quinazoline derivatives from various aldehydes, 2‐amino‐benzophenone, and ammonium acetate in good to excellent yields and new benzopyrano[2,3‐ d ]pyrimidine derivatives from salicylic aldehydes, various cyclic amines, and malononitrile in good to high yields.
