Weis, Robert published the artcileSynthesis of new analogs of diphenylpyraline, Application In Synthesis of 6972-05-0, the publication is Tetrahedron (2003), 59(9), 1403-1411, database is CAplus.
1-Unsubstituted 4-dimethylamino-5,6-dihydropyridine-2(1H)-thiones were converted to isomeric piperidin-4-ols which were separated and N-methylated to 2-substituted 1-methylpiperidin-4-ols. Their 1-Ph analogs were prepared from 4-dimethylamino-5,6-dihydro-1-phenylpyridine-2(1H)-thiones. After their conversion to dihydro-1-phenylpyridin-4(1H)-ones the hydrogenation gave isomeric 1-phenylpiperidin-4-ols, which were separated O-Alkylation of the 1-substituted piperidin-4-ols by various methods yielded 2-substituted analogs of diphenylpyraline. Their antimycobacterial activity was examined The configurations and conformations of the piperidine derivatives were investigated by NMR spectroscopy.
