Synthesis of podands functionalized with 2-oxo(sulfanylidene)-1,2,3,4-tetrahydropyrimidine and 4,7-dihydrotetrazolo[1,5-a]pyrimidine fragments

Abstract

Podands functionalized with 2-oxo(sulfanylidene)-1,2,3,4-tetrahydropyrimidine and 4,7-dihydrotetrazolo[1,5-a]pyrimidine fragments were synthesized by three-component condensation of N-(2-methylphenyl)-3-oxobutanamide with 2,2′-[2,2′-oxybis(ethane-2,1-diyl)bis(oxy)]dibenzaldehyde and urea (thiourea) or tetrazol-5-amine, respectively. The product structure was determined by IR and ¹H NMR spectroscopy and X-ray analysis.
