The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Regioselective C2-arylation of imidazo[4,5-b]pyridines, the main research direction is imidazopyridine regioselective arylation.Product Details of 58656-04-5.
We show that N3-MEM-protected imidazo[4,5-b]pyridines undergo efficient C2-functionalization via direct C-H arylation. Twenty-two substituted imidazo[4,5-b]pyridines are prepared and iterative, selective elaboration of functionalized imidazo[4,5-b]pyridines gives 2,7- and 2,6-disubstituted derivatives in good yields from common intermediates. Mechanistic observations are consistent with a concerted-metalation-deprotonation mechanism facilitated by coordination of copper(i)iodide to the imidazo[4,5-b]pyridine.
