1,2,5-Trimethyl-4-triphenylsilyl-4-piperidol was obtained and converted to 2,5-dimethyl-4-triphenylsilylpyridine. Several transformations of the isomeric piperidols isolated and of the substituted pyridines were examined.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1637–1641, December, 1970. 相似文献

5-Methyl-4-benzyl-2-styrylpyridine (II), its p-dimethylaminostyryl analog IV, and 5-methyl-4-benzyl-2-(1,3-dioxo-2-hydrindenyl)pyridine (V) have been prepared. II has been converted into 5-methyl-4-benzyl-2-phenylethynylpyridine (VII), 5-methyl-4-benzylpyridine-2-carboxylic acid (VIII), and 3-styryl-6, 7-benzoisoquinoline (X).Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1228–1231, September, 1970. 相似文献

5-Phenyl-9-bromotetrazolo[1, 5c]quinazoline (I) was synthesized. It was shown that I is covalently hydrated at the N(6)=C(5) bond. The structure of the covalent hydrate (V) was confirmed by cleavage to 5-(2-amino-5-bromophenyl) tetrazole. The probable mechanisms of the covalent hydration and cleavage are examined. V was converted to the 5-methyl derivative (VII).For part X, see [1]. 相似文献

Various substituted imidazo[4,5-b]pyridine analogues of Hoechst 33258 have been synthesized to explore the potential of selective helicase blockade and anticancer activity. The target compounds II a, b & d were obtained by condensation of the appropriate functionalized diamine and substituted benzimidazole aldehydes in nitrobenzene. 相似文献
