Abstract Oxidative removal of the dithioacetal group of several protected sugar and 2- acylamido-2-deoxy 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 (II) oxide or mercury dichloride—cadmium carbonate. In general, removal with N-bromosuccinimide proceeded more rapidly, and, with one ...
