1 H and 13 C NMR data for N ‐substituted morpholines 1 – 20 were measured using 1D (DEPT, 1D NOE difference) and 2D NMR spectroscopic methods including 1 H– 1 H COSY, long‐range 1 H– 1 H COSY, NOESY, gHMBC and gHMQC experiments. At room temperature the 1 H NMR spectra of protonated compounds 2 and 9 show the chair conformation for the morpholine ring. Spin–spin coupling constants were deduced from the resolution‐enhanced proton spectra. Copyright © 2005 John Wiley & Sons, Ltd.
