A full analysis of the PMR spectra of isomeric promedol alcohols was undertaken for the first time. It was shown that the conformational equilibrium must be taken into account only in the case of the Β isomer, where it is determined mainly by chair-

Publikováno v: Chemistry of Heterocyclic Compounds. 22:1107-1110

The condensation of 1,2,5-trimethylpiperidine-4-one with phenol and isomeric cresols yields 1,2,5-trimethyl-4-(p-hydroxyphenyl)- and (p-hydroxytolyl)-δ3-tetrahydropyridines, the structure and conformation of which have been studied by proton NMR spe

The fusion of 3,8-diphenyl-, 1,2-diphenyl-, and 6-methyl-2,7-diphenyl-indolizines with sulfur results in the formation of bis(indolizin-3-yl) disulfides with the respective substituents. Bis(2,8-diphenylindolizin-3-yl) disulfide is reduced to the ori
