Ureido sugars with eight various alkyl groups at N-3 were studied by means of ~H, ~3C, and 15N NMR spectroscopy in CDC13 solution and a 13C CP MAS technique in the solid state. The analysis of chemical shifts and coupling constants suggests the Z,Z-anti conformation of the ureido part of molecule. D
## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^βalkylβ__N__^2^βarylthioureas. The absence of decoalescence of the __N__^1^βalkyl group carbon signals down to 190 K, the europiumβinduced chemical shifts and the molecular mechanics calculations indicate that the preferred c
