2,3,5-Tri-O-(p-nitrobenzoyl)-β-D-ribofuranosyl bromide was reacted with p-chloro- and m-nitroanilines and the condensation products were N-acetylated.The structure of compounds 3-8 was established on the basis of the optical rotation measurements, CD curves, as well as the IR and 1H NMR spectral evidence.Conclusions referring to the conformational populations of N-acetyl-N-aryl-N-amines, published in our previous papers, have been supplemented by stating that the β-D-anomers assume one, whereas the α-D and β-L anomers two differenttypes of conformation of the furanose ring.
