Acetylation and benzoylation of oxazolo[4,5-b]pyridin-2(3H)-ones, 2-phenyloxazolo-[4,5-b]pyridines and pyrrolo[2,3-b]pyridin-2(2H)-ones were realised via reactions catalyzed with palladium.
## Reactions of 2,3-dihydro-4-oxo-thiopyrano[2,3-b] pyridine with aldehydes and with DMF-DMA furnished the 3-benzylidene and 3-(N,N-dimethylamino)-methylene derivatives. The latter products afforded spiro-pyrazolo-3,3 '-thiopyrano[2,3-b]pyridines and new tetra-and penta-heterocyclic ring systems
