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:
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 ...
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
NBoc-DMT, or NB-DMT, also known as N1-tert-butoxycarbonyl-N,N-dimethyltryptamine, is a serotonergic psychedelic of the tryptamine family. [ 1 ] [ 2 ] It is a novel designer and recreational drug and is a synthetic modification of dimethyltryptamine (DMT) with an N′ - tert -butyloxycarbonyl (NBoc) group .
Two principle protecting group schemes are typically used in solid phase peptide synthesis: so-called Boc/benzyl and Fmoc/tert-butyl approaches. [2] The Boc/Bzl strategy utilizes TFA -labile N-terminal Boc protection alongside side chain protection that is removed using anhydrous hydrogen fluoride during the final cleavage step (with ...
As each phenol group contains only a single t-butyl group they are considered to have low steric hindrance and thus high activity. Arranging three of these around an isocyanurate core gives a compound with a sufficiently high boiling point that it is not volatilised out of the plastic during plastic extrusion and moulding (up to 320 °C in the case of PA).

Di-tert-butyl-iminodicarboxylate is an organic compound that can be described with the formula [(CH 3) 3 COC(O)] 2 NH. It is a white solid that is soluble in organic solvents. The compound is used as a reagent for the preparation of primary amines from alkyl halides. [1] It was popularized as an alternative to the Gabriel synthesis for the same ...
