Constructing New Bioorthogonal Reagents and Reactions

Transmetalation Reactions Producing Organocopper Reagents

Organocopper reagents constitute a key class of organometallic reagents, with numerous applications in organic synthesis [1]. Their high reactivities and chemoselectivities have made them unique intermediates. Most reports use organocopper reagents of type 1 or 2, which are prepared from organolithiums. This transmetalation procedure confers optimal reactivity, but in many cases it permits only...

Development of bioorthogonal reactions and their applications in bioconjugation.

Biomolecule labeling using chemical probes with specific biological activities has played important roles for the elucidation of complicated biological processes. Selective bioconjugation strategies are highly-demanded in the construction of various small-molecule probes to explore complex biological systems. Bioorthogonal reactions that undergo fast and selective ligation under bio-compatible ...

From Mechanism to Mouse: A Tale of Two Bioorthogonal Reactions

Bioorthogonal reactions are chemical reactions that neither interact with nor interfere with a biological system. The participating functional groups must be inert to biological moieties, must selectively reactive with each other under biocompatible conditions, and, for in vivo applications, must be nontoxic to cells and organisms. Additionally, it is helpful if one reactive group is small and ...

Antigen – Antibody Reactions with Labeled Reagents

Reactions of iodine-nitrene reagents with boranes.

Reactions of the boranes (C6F5)2BR (R = C6F5, Ph, H) with the nitrene-iodine reagents XC6H4SO2N=IPh, X = Me, Cl and MeSO2N=IPh effect the insertion of nitrene into the B–C and B–H bonds affording the species (C6F5)2BN(SO2C6H4X)R (X = Me, R = C6F5 1, Ph 3, H, 4, X = Cl, 5, X = NO2, 7) and (C6F5)2BN(SO2Me)H 6).
