Isobe and co-workers reported that some a-aromatic secondary alcohols show irregular Δδ values for the β-protons in the modified Mosher method, presumably due to the anisotropic effects of the aaromatic groups. They also reported that these irregular data can be neglected for determination of the absolute configuration by the modified Mosher method. Some of our [2,3]-Wittig products also exhibited the same irregular Δδ values for the β-protons and the absolute configurations were assigned according to Isobe's report; see I. Ohtani, K. Hotta, Y Ichikawa, M. Isobe, Chem. Lett. 1995, 513-514.
