3H-Pyrazolo[1, 5-a]indole derivatives were propared for the first time starting from 3-oxo-2-phenyl-3H-pyrazolo[1, 5-a]indole, which was obtained by the 2, 3-dichloro-4, 5-dicyano-p-benzoquinone (DDQ) oxidation of 3-hydroxy-2-phenyl-3a, 4-dihydro-3H-pyrazolo[1, 5-a]indole. Their reactions were briefly investigated.
以3-氧代-2-苯基-3H-吡唑并[1, 5-a]吲哚为原料,首次合成了3H-吡唑并[1, 5-a]吲哚衍生物,该衍生物是由2, 3-二氯3-羟基-2-苯基-3a, 4-二氢-3H-吡唑并[1, 5-a]吲哚的-4, 5-二氰基-对苯醌 (DDQ) 氧化。他们的反应被简要调查。
