1,3,4-Oxadiazole-2-thione was prepared by decarboxylation of the corresponding 5-carboxylic acid. Spectral data supported the predominant, if not exclusive, existence of the thione form in solution.

It is shown that the sodium hydride (in dimethyl formamide) induced elimination of hydrogen bromide from 1,3-dibromo-2-(tetrahydropyran-2-yloxy)propane (3) can be considered to result in the in situ formation of 3-bromo-2-(tetrahydropyran-2-yloxy)pro

The base-induced alkylation of 4-unsubstituted homophthalimides with 1-bromo-2-chloroethane produced the spirocyclopropane compounds 4. The structures of these compounds were supported by their spectral properties and by their susceptibility towards

The electrophilic substitution of N-alkylated isocarbostyrils was examined in considerable detail. Bromination, acylation, nitration, and acid-catalyzed condensation with formaldehyde occurred exclusively at C-4 under relatively mild conditions. The

It was shown that 3-phenyl-3-(2-aminoethyl)phthalide (6, R = H) and its N-methyl analog (6, R = CH3) existed in the amino lactone form in solution at room temperature. In the absence of solvents, however, these compounds underwent a spontaneous trans

The sulfuric acid catalyzed acylation of 2-methyl-5-nitroisocarbostyril with carboxylic acid anhydrides gave the corresponding 4-acylated derivatives 3, which underwent reductive cyclization to 2-substituted derivatives of 4-methyl-1,3,4,5-tetrahydro
