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 From analysis and refinement by the LAOCOON III program of the 220 MHz ^1^H spectrum of 2,2β²βbiquinoline, recorded as a saturated solution in carbon disulphide, most derived chemical shifts and coupling constants are close to corresponding values in quinoline. However, Hβ3 is at 1.5 ppm
