✦ Synopsis

Oxidative removal of the dithioacetal group of several protected sugar and 2acylamido-Zdeoxy sugar dialkyl dithioacetals with N-bromosuccinimide in 97% aqueous acetone or 1: 1 (v/v) 2-methyl-2-propanol-acetone was compared with removal with mercury dichloride-mercury(I1) oxide or mercury dichloride-cadmium carbonate. In general, removal with N-bromosuccinimide proceeded more rapidly, and, with one exception, yields were higher than or equal to those obtained with the method using mercury salt.

Radical bromination of 4,5-dimethylthiazole (1) was carried out using different stoichiometries of N-bromosuccinimide in the presence of 2,2Ј-azobisisobutyronitrile. Mono-, tri-and tetrabromo compounds 2, 5, and 6 were obtained in good yields with regioselectivity while the dibromo derivatives 3 and
