1, 2-Benzenediols were synthesized via 1, 1-bis(ethylthio)-3-cyclohexen-2-one derivatives, which were prepared by condensation of 1, 1-bis(ethylthio)-2-propanone with Mannich bases. Regioselective preparation of their monoethers was also achieved.

Alicyclic 1,5,9-triketones with various combination of 5-, 6-, 7-membereded cycles in the molecule were obtained by methods of diketone condensation, Michael reaction, and proceeding from Mannich mono- and bisbases and cycloalkanones. The latter method was accompanied with a transaminomethylation, observed for the first time at triketones preparation. The structures of cyclic forms of Michael reaction
Further exploration of 1-{2-[Bis-(4-fluorophenyl)methoxy]ethyl}piperazine (GBR 12909): role of N-aromatic, N-heteroaromatic, and 3-oxygenated N-phenylpropyl substituents on affinity for the dopamine and serotonin transporter

N-phenylpropyl derivatives of 1-(2-benzhydryloxyethyl)-piperazine and 1-[2-[bis-(4-fluorophenyl)methoxy]ethyl]piperazine, analogues of GBR 12909 (1a) and 12935 (1b), was synthesized and examined for their dopamine (DAT) and serotonin (SERT) transporter binding properties. One of these compounds, racemic 3-[4-(2-benzhydryloxyethyl)piperazin-1-yl]-1-(3-fluorophenyl)-propan-1-ol (33), had DAT affinity as good as

Mannich bases obtainedfrom cycloalkanones and methyl-ketones decompose on heating to give α,β-enones, which react in situ with nonstabilized azomethine ylides formed from spiro[anthracene-oxazolidines]. The final products, 3-acylpyrrolidines, were obtained in yields of 21–79% by heating the starting compounds in a microwave reactor in o-xylene at 210 °C for 45 min
