Research paper thumbnail of Unexpected diastereotopic behaviour in the ¹H NMR spectrum of 1,4-dihydropyridine derivatives triggered by chiral and prochiral centres

We have synthesised a series 4-(5'-nitro-2'-furyl)-1,4-dihydropyridine derivatives, which were characterised by 1H-NMR. We have found that carboethoxy groups at the C-3 and C-5 on the 1,4-dihydropyridine ring show a much more complex signal in the 1H NMR spectra, either when C-4 is a pseudo-prochiral or a chiral centre.
