摘要：

The reactions of azine ylides 1 with isocyanates, ketenes, and other species that contain carbonyl or thiocarbonyl moieties have been shown to provide excellent syntheses of a variety of pyrazolo-fused heterocyclic compounds1-9 such as pyrazolo[5,l-c]oxazines, and 4,9-dihydropyrazolo-[l,5-b]isoquinolines,1,2 4H-pyrazolo[l,5-c] [l,3,5]oxadiaz-ines,4 and 4,5-dihydro- and 6,7-dihydropyrazolo[l,5-α]-pyridines5. © 1990, American Chemical Society.
