The Tavs reaction of 2-amino- and 2-acylamido-3-bromopyr-idines 1 and 2 with triethyl phosphite in the presence of palladium, acetate or chloride allows the synthesis of 2-aminoand 2-acylamidopyridine-3-phosphonates 3 and 4. A second ring nitrogen atom ca

Starting from commercially available halonitropyridines and haloaminopyridines, 2-substituted-oxazolo[5,4-b]pyridines, and 2-aryl-oxazolo[4,5-b]pyridines were synthesized in good yields by using a Cu(I)-mediated cyclization of halopyridylamides as a key step. Georg Thieme Verlag Stuttgart.
