#dicarbonate

Di-tert-butyl dicarbonate is a element widely used in organic mixture. This carbonate ester reacts with amines in order to give N-tert-butoxycarbonyl baton so-called t-BOC derivatives. These derivatives do not behave as amines, which allows certain postpositional transformations to occur that would have otherwise affected the amine tagmemic string orchestra. The t-BOC heap up forthcoming endure removed out of the amine using acids. Thus, t-BOC serves as a prophylactic match.<\p>
