Abstract: | The reaction of 2-ethoxycarbonyl-3-ketoquinuclidine with arylhydrazines has been examined It is shown that the first stage in the reaction is the formation of 2-ethoxycarbonyl-3-(-arylhydrazino)-2-dehydroquinuclidines, which are then converted into 2-aryl-3-hydroxy-pyrazolo[4, 3-b]quinuclidines (III). The O-methyl- and O-benzoyl- derivatives of III have been synthesized.Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1261–1263, September, 1970. |
