Özet

An efficient protocol was developed for the four component and one-pot synthesis of functionalized 1, 4-dihydropyridines by thiamine (VB1) as biocatalyst via the reaction of malononitrile, substituted aldehydes, dimethylacetylenedicarboxylate and substituted aniline in ethanol at room temperature. Availability and non-toxicity are from important advantages of this green catalyst. Also, easy work-up, no chromatographic purifications and high yields in short reaction time are othere benefites of this procedure.
