설명

일반 설명

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.

애플리케이션

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

Used to cleave aryl methyl ethers in a synthesis of a benzopyranobenzopyran from a coumarin scaffold.
