Staudinger azide reduction
WebFeb 16, 2015 · In 2000, azide was metabolized into cell-surface glycans through N-azidoacetylmannosamine (Ac4ManNAz) by Bertozzi, and Staudinger ligation with a biotinylated triarylphosphine was then performed to form stable adducts on the cell surface . This is the first example of glycan labeling through bioorthogonal chemistry. WebAug 16, 2013 · Several azide-derivatized and fluorescently-labeled peptides were immobilized on azadibenzocyclooctyne (ADIBO)-activated slide surfaces via a strain-promoted alkyne-azide cycloaddition (SPAAC) reaction revealing excellent immobilization kinetics, good spot homogeneities and reproducible fluorescence signal intensities.

Webproducts. In the traceless Staudinger ligation, however, the reduction of the azide to amine is a competing side reaction, thus reversing the capture step and leading to two peptide fragments.4 We envisioned that placing an electrophile and an azide rather than the former and phosphine within the same molecule would allow for acyl transfer and ... WebA separate trigger probe carrying a phosphine group is designed to reduce the azide. Author Manuscript Templated chemistry allows positioning of the two reacting groups in close proximity, resulting in azide reduction and rapid linker hydrolysis, thus releasing the quencher and activating the fluorophore.
WebAn efficient catalytic Staudinger reduction at room temperature provides structurally diverse amines from azides in excellent yields in the presence of catalytic amounts of triphenylphosphine and diphenyldisiloxane as terminal reducing agent. The reaction exhibits high chemoselectivity and tolerates nitriles, alkenes, alkynes, esters, and ketones.
