  Syntheses of Spiro(oxazolidinediones): Spiro[1H-isoindole-1,5'-oxazolidine]-2',3(2H),4'-triones and Spiro[1,2-benzisothiazole-3(2H),5'-oxazolidine]-2',4'-dione 1,1-Dioxides

  摘要：

  Members of two novel families of spiro(oxazolidinediones) have been prepared. Spiro[1H-isoindole-1,5'-oxazolidine]-2', 3(2H),4'-triones (4) were synthesized from the corresponding 1-hydroxy-1-carboxyethylisoindol-3-one (7) or (10) or their primary amide derivatives (14). In turn 7 and 10 were prepared from 2-bromobenzoic acid amides (6) and (9). or from N-alkylated isoquinolin-1, 3, 4(2H)-triones (12). Spiro[1, 2-benzisothiazole-3(2H), 5'-oxazolidine]-2', 4'-dione 1, 1-dioxides (5) were constructed from the appropriate 2,3-dihydro-3-hydroxy-1,2-benzisothiazole-3-carboxamide 1,1-dioxide (17). The immediate precursors to 14, ethyl esters (16) and (19), were prepared from benzenesulfonamide (15), or from 2-bromobenzenesulfonamide (18).
