4–Aryl–1,4–dihydropyridines are analogues of NADH coenzymes, which have been explored for their calcium channel activity. Density functional theory calculations have been performed to determine the hardness (η), chemical potential (μ) and electrophilicity (ω) energy molecules. The aim of present studies is to focus on the structural optimization, electronic properties of some ethyl 4–aryl–1,4–dihydropyrdin–3,5–dicarboxylate(DHPs) by using density functional theory. Results of this study show that in these DHPs the electronic parameters are depends on the nature of the substituent at the C4 position.<\div>

P2O5–SiO2 (30% w\w) was found to be a useful catalyst for the synthesis of various 2–substituted aryl benzimidazoles under solvent–less and in solvent conditions from o–phenylenediamine and aldehydes. The products were directly recrystallized from methanol.

۳Urea–hydrogen peroxide\silica phosphoric acid–catalyzed oxidation– condensation Tandem reaction: One–pot synthesis of 2–substituted benzimidazoles from alcohols

تعداد صفحات: ۵
An efficient one–pot oxidation\condensation tandem process has been developed for the synthesis of 2–substituted benzimidazole derivatives from benzylic alcohols and 1,2–phenylenediamine with use of urea–hydrogen peroxide\silica phosphoric acid as a bifunctional catalyst. This method provides a rapid and efficient access to 2–substituted benzimidazoles.
