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:
Tert-Butylamine; Butylated hydroxyanisole; Butylated hydroxytoluene; 4-tert-Butylbenzaldehyde; N-tert-Butylbenzenesulfinimidoyl chloride; Para-tert-Butylbenzoic acid; 4-tert-Butylcatechol; Tert-Butyldiphenylsilyl; Tert-Butylhydroquinone; Tert-Butyllithium; Tert-Butyloxycarbonyl protecting group; Tert-Butylphosphaacetylene; Tert-Butylthiol; N-t ...
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
Gelators serve as stabilizers and thickeners, thickening the gel solution while simultaneously maintaining the gel’s flexible nature. [8] When dispersed through the solvent as a colloid, gelators offer a stable internal structure to the gel. [8] Gelators are usually chosen based on their affinity for the solvent and the purpose of the gel. [5]
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a chemical compound used as a polymer stabilizer in plastics. Like other hindered phenols it acts as a primary antioxidant . More than 1000 tonnes per year are used in the EU.
A 2002 review found "some reports indicate that inappropriate BC (barrier cream) application might induce a deleterious rather than a beneficial effect." [6] Skin that has been moisturized by barrier cream may be more susceptible to irritation by sodium lauryl sulfate, which can permeate hydrated skin more easily due to its hydrophilia. [5]
