An unusual reaction where an allylic methylene is converted into an ethyl ester by means of Wohl-Ziegler's reagents is presented : The reaction of 4-acetyl-1-methyl-2-phenyl-1,2,3,10-tetrahydro-4H-pyrazolo [3,4-c] [1,5] benzothiazepin-3-one (7) with N-bromosuccinimide or N-bromoacetamide in commercial (ethanol-containing) chloroform gave ethyl 3-acetyl-5'-oxo-1'-phenyl-spiro [benzothiazoline-2,4'-[2] pyrazoline]-3'-carboxylate (8). Similarly ethyl 3,5'-dioxo-1'-phenyl-spiro [benzo [b] thiophene-2 (3H), 4'-[2] pyrazoline]-3'-carboxylate (11) was obtained from 1-methyl-2-phenyl-1,2,3,10-tetrahydro-4H-pyrazolo [3,4-c] [1] benzothiepin-3,4-dione (10).
