摘要：
Values of 3 J(CC), 3J(CH), 4J(CH) and 3J(HH), supported by n.O.enhancements, in nmr spectra of 2-methoxy- and 2-methyl-amino-tetrahydropyrans, point to a very strong preference for rotamers in which an exo-cyclic heteroatom lone pair is antiperiplanar to the endo-cyclic C2-O bond ("exo-anomeric effect"). © 1990.
