WitrynaThe tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group (BOC group) is a protecting group used in organic synthesis.. The BOC group can be added to the amine under aqueous conditions using di-tert-butyl dicarbonate in the presence of a base such as sodium carbonate: . Protection of the amine can also be … WitrynaFor example, tert-butanol is less potent as a nucleophile than methanol. This is because the comparatively bulky methyl groups on the tertiary alcohol effectively block the route of attack by the nucleophilic oxygen, slowing the reaction down considerably (imagine trying to walk through a narrow doorway while carrying three large suitcases!).
WitrynaThe nature of the electron-rich species is also critical. Acetate, for example, is a weak base but a reasonably good nucleophile, and will react with 2-bromopropane mainly as a nucleophile. In order to direct the reaction towards elimination, a strong hindered base such as tert-butoxide can be used. The bulkiness of tert-butoxide makes it ...
