This study presents a synthesis of new series of some benzimidazole, bisbenzimidazole and perimidine derivatives viamicrowavetechnique, which, leads to the good product yields and short reaction times. The structure of newly synthesized compounds was confirmed by 1H NMR and 13C NMR spectra. These compounds were screened for their lipase inhibition activity. Then, all compounds were evaluated with
procedure is described for the synthesis of 2-substituted perimidines involving the reaction of 1,8-diaminonapthalene with iminoester hydrochlorides of substituted phenylacetic acids under microwave irradiation. This leads to good yields in short reaction times. The results were compared with those that used conventional heating. This new method may be preferable for the synthesis of perimidines.

A short synthesis of 2-amino-7, 8-dimethoxy-1H-3-benzazepine (1a) from 3, 4-dimethoxyphenylacetonitrile (8a) is reported. The synthesis of several other 2-amino-1H-3-benzazepines 1 is also discussed. Conditions which favor the formation of 1 versus the formation of the isomeric 2-benzylimidazoles 11 are evaluated. Several reactions of 1a are also described.

We have previously reported substituted 2-aryl-thiazolidine-4-carboxylic acid amides as potent and selective antiproliferative agents for melanoma. To understand the importance of the thiazolidine ring and to reduce potential complications associated with the two chiral centers, we designed and synthesized sets of new analogs by modifying this ring. These new analogs were tested in two melanoma cell
