Abstract: | The reactions of 2-aryl(hetaryl)methylene-3-oxoquinuclidines with hydrazine hydrate, thiourea, and phenylhydrazine gave, respectively, 7-phenyl-7,7a,dihydropyrazolo3,4-b]quinuclidine, 7-(4 -methoxyphenyl)-7,7a-dihydropyrazolo3,4-b]quinuclidine, 7-(2 -thienyl)-7,7a-dihydropyrazolo-3,4-b]quinuclidine, 3,3 -azinobis (2-benzylidenequinuclidine), 3,3 -azinobis2-(4 -methoxybenzylidene)quinuclidine], 6-thio-8-phenyl-5,6,7,8-tetrahydropyrimido5,4-b]quinuclidine, 2-benzylidene -3-oxoquinuclidine phenylhydrazone, and 2-(4 -methoxybenzylidene)-3-oxoquinuclidine phenylhydrazone. The structures of the compounds were confirmed by the IR and 1H and 13C NMR spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 793–797, June, 1982. |
