The oxidative palladium-catalyzed cross-coupling of pyrimidines containing pyridotriazol-1-yloxy (OPt) as either a urea or an amide functional group with arylboronic acids in the presence of Cs2CO3 in DME containing 0.6-1.0% H2O is described for the preparation of heteroaryl ethers. The bromo substitution in the case of 3-(5-bromo-pyrimidin-2-yloxy)-3H-[1,2,3]triazolo[4,5-b]pyridine could serve as a handle for further elaborations such as Suzuki coupling for attaching varied aryl groups. 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: 156311-83-0Formula: C17H27F6N7OP2).
((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. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Formula: C17H27F6N7OP2
