Treatment of N-(arylsulphonyloxy)-1-phenylnaphthalene-2,3-dicarboximides (IIa, b) with ammonia, aromatic amines, amino acids and hydrazine hydrate brings about the imide ring opening followed by Lossen rearrangement to give benzoquinazoline-2,4-diones (IIIa-h) and the salts of arylsulphonic acids (IVa-p).
