The b-carbon resonances of 23 Z-substituted adamantanes were assigned unequivocally by two-dimensional (ZD) correlated NMR spectroscopy. It is shown that in contrast to all previously published instances the 6 carbon signal sequence is reversed for 10 other substituents. 2 1 -\_x' -y\* 'Y3 Since the

✦ Synopsis
Two-dimensional INADEQUATE NMR spectroscopy was used to assign unequivocally the syr~ and anti 6 13C resonances of 2-substituted adamantanes.
-Adamantanes, being well-defined geometrically, minimally strained, and conformationally rigid,
