((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0) belongs to triazole derivatives. Triazoles consist of a five-membered ring containing three nitrogen atoms and are biologically active, especially as antifungal, antimicrobial and enzyme inhibitors. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Quality Control of ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V)
Peptide thioacylation with high stereochemical preservation was written by Hoeg-Jensen, Thomas;Holm, Arne;Sorensen, Hilmer. And the article was included in Synthesis in 1996.Quality Control of ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) The following contents are mentioned in the article:
A dipeptide thioamide model system, Boc-Leu-ψ[CSNH]-Met-OMe, was used for evaluating the preservation of amino acid stereochem. during thioacylation utilizing amino monothio acids. The LL and DL peptide diastereomers were separated by use of high performance capillary electrophoresis (micellar electrokinetic capillary chromatog.). This thioacylation method combines monothio acids with coupling reagents of the PyBOP-family for generating active thiono esters with low-levels of enantiomerization (<2%). The best results in terms of stereochem. preservation and yield were obtained with PyNOP, a 6-nitro analog of PBOP. The successful activation of thiobenzoic acid with all 4 coupling reagents extended the scope of the method to include aryl monothio acids. This study involved multiple reactions and reactants, such as ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V) (cas: 156311-83-0Quality Control of ((3H-[1,2,3]Triazolo[4,5-b]pyridin-3-yl)oxy)tri(pyrrolidin-1-yl)phosphonium hexafluorophosphate(V)).
