A zeolite promoted expeditious one-pot synthesis of 1-arylmethyl-4,5-dihydro-2-aryl-1H-imidazole
摘要:
Abstractmagnified image A series of 1‐arylmethyl‐4,5‐dihydro‐2‐aryl‐1H‐imidazoles were synthesized expeditiously in good yields from 1,2‐diaminoethane and aromatic aldehydes in the presence of zeolite under microwave irradiation in the absence of solvent. The resulting substituted imidazoles are characterized by 1H and 13C NMR, elemental analysis, and mass spectral data. J. Heterocyclic Chem., (2010)

A simple, highly efficient and environmentally friendly microwave accelerated one-potsynthesis of a series of differently substituted bis-azetidinones have been synthesized expeditiously in good yields from 1,2-diaminoethane and aromatic aldehydes in the presence of zeolite. The structures of the newly synthesized compounds were confirmed by IR, NMR, and mass spectra. The design and calculated molecular
In this note, the synthesis and structure-activity relationships of a new series of 2R,2'R/2S,2'S and 2R,2'S-meso 3,3'-(1,2-ethanediyl)-bis[2-aryl-4-thiazolidinones] are described. Antiinflammatory activity was investigated by the carrageenin-induced paw edema test and analgesic activity by aceticacid writhing and hot plate tests in rats. All compounds displayed ulcerogenic effects and acute toxicity
