DESCRIPTION
General description
Di-tert-butyl dicarbonate (Boc2O) is a reagent mainly used for the introduction of the Boc protecting group to amine functionalities. It is also used as a dehydrating agent in some organic reactions, particularly with carboxylic acids, certain hydroxyl groups, or with primary nitroalkanes.
Application
Di-tert-butyl dicarbonate (Boc2O) has been used in the synthesis of:
- An azobenzene amino acid(aa).
- N-tert-butoxycarbonyl-3,4-methylenedioxymethamphetamine (t-BOC-MDMA) from MDMA.
It can also be used as a reagent:
- To introduce acid-labile Boc-protecting group in amino acids, peptides, and proteins.
- To prepare styrene derivatives by Heck olefination of aromatic carboxylic acids in the presence of a Pd catalyst.
- To synthesize oxazolidin-2-ones and imidazolidin-2-ones by isocyanation of 1,2-aminoalcohols and 1,2-diamines using DMAP as a catalyst.
- In the preparation of N-tert-butoxycarbonyl-3,4-methylenedioxymethamphetamine (t-Boc-MDMA) from MDMA.
- For the conversion of amines to corresponding isocyanates, carbamates, and urea derivatives.
- In the N-BOC-ylation of amides.
- In the N-BOC-ylation of sensitive compounds under non-aqueous conditions.
- Reagent for the introduction of the Boc protecting group.
