The relative configuration of a methylated undecanehexaol, a fragment of amycin B, with five chirality centers was determined by a complete 1 H and 13 C signal assignment and interpretation of its acetonide derivatives.

โฆ Synopsis
The anomeric configuration of sialic acid and its derivatives could be determined on the basis of the coupling pattern of C-l in the gated proton-decoupled or selective proton decoupled "C-NMR spectra; the a! anomer gave a doublet C-l signal while the fi gave a singlet.
Recently much interest has been taken in the chemistry and biochemistry of sialic acids (a! 1 and fi 1) and the related compounds 1). Determination of

## Abstract Carbonโ13, carbonโ13 oneโbound and longโrange coupling constants are determined for anthracene and 9,10โdihydroanthracene labelled in the 9,10โpositions, and for thiophthalic anhydride and phthalimide, labelled in both carbonyl groups. Relative signs are determined by the SDL method. Si
Both 13C-and 15N-REDOR experiments were performed to determine the '3C-'5N interatomic distance in [ I-"C]N-acetyl-Pro-[ '5N]GIy-Phe crystal and to evaluate the inter-or intra-molecular dipolar contributions leading to its errors. The interatomic distance was determined to be 3.43 8, after removing
