2,4-DIARYL-2,3-DIHYDROBENZOTHIAZEPINES

2,4-Diaryl-2,3-dihydrobenzothiazepines are obtained in a single stage from chalcones and ortho-aminothiophenol in the presence of triethylamine.The nature of the electronic transitions in their UV absorption spectra is discussed with the use of quantum-chemical methods.It was shown that the seven-membered ring does not invert in the range of temperatures between -80 and +140 deg C and is in the boat form.The main initial event in the fragmentation of the molecules of the obtained compounds under electron impact is the formation of benzothiazole-containing radicalions.In an acidic medium 2,4-diphenyl-2,3-dihydrobenzothiazepine is hydrolyzed to 3-(2-aminophenylthio)-1,3-diphenyl-1-propanone, and in its reaction with 2,4-dinitrophenylhydrazine chalcone hydrazone and o-aminothiophenol are formed.

Regioselective synthesis of 1,3,5-trisubstituted pyrazoles

A new and a simple approach toward synthesis of 1,3,5-trisubstituted pyrazoles from chalcone arylhydrazones via oxidative cyclization has been achieved. 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone was successfully used as an oxidizing agent to give excellen

Chemical transformations of 2,4-diaryl-2,3-dihydro-1H,1,5-benzodiazepines

The behavior of 2,4-diphenyl-2,3-dihydro-1H-1,5-benzodiazepine in acylation, alkylation, nitrosation, oxidation, reduction, salt formation, and opening of the diazepine ring under the influence of various dinucleophiles and acids was studied. It is shown that the dihydrodiazepine ring is extremely sensitive to acidic reagents and undergoes rearrangement to an imidazole ring under their influence. The structure of the cis- and trans-tetrahydroazepines were analyzed thoroughly.
