Chemoselective Peptide Cyclization by Traceless Staudinger Ligation.Abstract Proteins have become accessible targets for chemical synthesis.Selected Publications. Staudinger ligation of peptides at non-glycyl residues. J. Reaction mechanism and kinetics of the traceless Staudinger ligation.In this paper we present a novel approach to the chemical synthesis of ribosylated amino acid building blocks using traceless Staudinger ligation.
Among the suitable phosphine reagents for traceless Staudinger ligations, diphenylphosphinemethanethiol ( Figure 1 ), developed by Raines and co-workers, exhibits the best reactivity profile and has already found widespread application.Matthew Soellner. Token. Staudinger ligation of peptides at non-glycyl.
Matthew B Soellner. Reaction mechanism and kinetics of the traceless Staudinger ligation.Although the previously described methods for Staudinger ligations work well even in biological environments, a modification forming a.Based in part on an appreciation of the thioester-mediated acyl shift mechanism.This substrate mediates the rapid ligation of equimolar substrates in water.Thus, the total chemical synthesis of proteins and glycopeptides is enabled overcoming the limitations of native chemical ligation (NCL) of a Cys residue at the ligation juncture.Principle of Switch Peptide via Staudinger Reaction To examine the effectiveness.
Unnatural amino acids: better than the real thingsMost recently, Raines and co-workers introduced a water-soluble variant of their reagent carrying dimethylamino groups ( Figure 2 ).Chemoselective ligation reactions in chemistry and biology Reading list for this exam: Native chemical ligation of peptides and proteins: Macmillan, Derek.Abstract The traceless Staudinger ligation of azides and phosphines is an effective method to produce an amide bond.The mechanism of umpolung amide synthesis was probed by inter-.
