✦ Synopsis

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 when treated with nitrilimines and aminoazoles, respectively. A number of the products showed high antifungal and antibacterial activities.
