General description
Boron tribromide is a strong Lewis acid generally employed in the deprotection of -OH and -NH groups. It is a moisture-sensitive liquid, which is also used to cleave esters or ethers into alkyl bromides.
Application
Used to cleave aryl methyl ethers in a synthesis of a benzopyranobenzopyran from a coumarin scaffold.
Reactant for preparation of:
- Drug intermediate 6-nitro-L-DOPA
- Luminescent polystyrene derivatives with sterically protected carbazolylborane moieties
- High-quality boron-doped graphene via Wurtz-type reductive coupling reaction
- Mercapto-(+)-methamphetamine haptens for synthesis of (+)-methamphetamine conjugate vaccines with improved epitope densities
- Micrometer-sized organic molecule-DNA hybrid structures
- Borane complexes via electrophilic aromatic borylation reactions
- A 5-HT2C receptor agonist
- Biphenyl-derivatives possessing tertiary amino groups as β-secretase(BACE1) inhibitors for the treatment of Alzheimer′s disease
- A highly near-IR region fluorescent p-extended boron aza-dipyrromethene moiety unit
- Tetrahydroisoquinoline derivatives via intramolecular cyclization of methoxy-substituted N-phenethylimides
