Reaction of 5-ethylamino-3-phenylpyrazole with dicarboxylic acid anhydrides in tetrahydrofuran in the presence of 1,3-dicyclohexylcarbodiimide, afforded bicyclic and tricyclic derivatives of pyrazolo[1,5-a][1,3]-diazepines. The tricyclic derivatives constitute a new class of compounds. Characterisation of these products was effected with ir, pmr, and 13C nmr spectral data.
在1,3-二环己基碳二亚胺存在下,5-乙基氨基-3-苯基吡唑与二羧酸酐在四氢呋喃中反应,得到吡唑并[1,5- a ] [1,3]-二氮杂卓的双环和三环衍生物。三环衍生物构成一类新的化合物。这些产品的表征是通过ir,pmr和13 C nmr光谱数据进行的。
