Data are reported on spin-lattice relaxation-rates and nuclear Overhauser enhancement of protons of exo and endo diastereoisomers of 1,2-O-(1-methoxyethylidene) and 1,2-O-(1-benzyloxyethylidene) derivatives of 3,4,6-tri-O-acetyl-β-D-mannopyranose, and of some specifically deuterated analogs of these derivatives.The results verified assignments of the orientation at the quaternary carbon atom of the acetal ring, and yielded information about the orientations favored by the exocyclic C-methyl and benzyloxy substituents.
