Abstract

Proton and carbon chemical shift data and proton–proton coupling constants of the synthetic antithrombotic pentasaccharide SanOrg34006 and its synthetic precursors are reported. Long‐range heteronuclear correlation experiments allow the determination of the substitution pattern of the protecting groups in the precursor molecules. Also, the sequence of the oligosaccharide was confirmed this way. The conformation of the α‐L‐iduronic acid moiety was studied by the analysis of the ^3^J(^1^H,^1^H) coupling constants.

The rare alkaloid casimiroedine and its peracetylated derivative both show complex 1 H and 13 C spectra with almost all signals doubled owing to slow rotation about the amide bond. Nevertheless, it is possible, using 2D NMR methods, to assign fully the 1 H and 13 C spectra of the major and minor con
