2. tert-Butyloxycarbonyl protecting group - Wikipedia

   en.wikipedia.org/wiki/Tert-butyloxycarbonyl...

   tert-Butyloxycarbonyl protecting group. The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di-tert-butyl dicarbonate in the presence of a base such as sodium hydroxide:

3. Di-tert-butyl dicarbonate - Wikipedia

   en.wikipedia.org/wiki/Di-tert-butyl_dicarbonate

   Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. [1] Since this compound can be regarded formally as the acid anhydride derived from a tert-butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride. This pyrocarbonate reacts with amines to give N-tert-butoxycarbonyl or so-called Boc

4. Protecting group - Wikipedia

   en.wikipedia.org/wiki/Protecting_group

   The tert-butyloxycarbonyl group is marked blue. Amines have a special importance in peptide synthesis, but are a quite potent nucleophile and also relatively strong bases. These characteristics imply that new protecting groups for amines are always under development. [47] Amine groups are primarily protected through acylation, typically as a ...

   The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
