Pyrazole-fused cyclic anhydrides have been employed for the first time as the Castagnoli–Cushman reaction partners to produce hitherto unknown 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazine-7-carboxylates in remarkably convenient and speedy fashion. Attempts to realize the same chemistry with indole and benzimidazole analogues failed.

唑稠环酸酐以 Castagnoli-Cushman 方式反应的第一个例子

吡唑稠合环酐首次被用作 Castagnoli-Cushman 反应伙伴，以显着地制备迄今为止未知的 4-oxo-4,5,6,7-四氢吡唑并[1,5-a]pyrazine-7-carboxylates方便快捷的时尚。用吲哚和苯并咪唑类似物实现相同化学反应的尝试失败了。
