产品详细信息

详细说明 (English)
Packaging
5, 25, 100 g in ampule
Application
Reactant for preparation of:
• Drug intermediate 6-nitro-L-DOPA1
• Luminescent polystyrene derivatives with sterically protected carbazolylborane moieties2
• High-quality boron-doped graphene via Wurtz-type reductive coupling reaction3
• Mercapto-(+)-methamphetamine haptens for synthesis of (+)-methamphetamine conjugate vaccines with improved epitope densities4
• Micrometer-sized organic molecule-DNA hybrid structures5
• Borane complexes via electrophilic aromatic borylation reactions6
• A 5-HT2C receptor agonist7
• Biphenyl-derivatives possessing tertiary amino groups as β-secretase(BACE1) inhibitors for the treatment of Alzheimer′s disease8
• A highly near-IR region fluorescent p-extended boron aza-dipyrromethene moiety unit9
• Tetrahydroisoquinoline derivatives via intramolecular cyclization of methoxy-substituted N-phenethylimides10
With alkynes forms 2-alkenyldibromoboranes, which show reversed regiochemistry in Diels-Alder reactions as compared to BBN. Intermediates generated from 1-alkynes couple to alkyl halides providing trisubstituted alkenes. Reacts with chiral sulfonamides to provide precursors of chiral glycidol esters, acetate diols, β-hydroxy esters, and amino acid esters. Useful for the synthesis of precursors to group 13-15 semiconductor materials.
