Abstract
A comparison of steady-state NOE coefficients measured for 3-O-allenyl-subs tituted furanoses in [H-2(8)]toluene solution with conformations generated by a molecular mechanics program allowed characterisation of the most favou rable ground state conformations. The geometry assigned from NOE coefficien ts corresponds well to that obtained by X-ray structure analysis of allene 1.
