## Abstract From the chloroform extract of __Austroplenckia populnea__, epikatonic acid, friedelin, populnonic acid, abruslactone A, salaspermic acid and 22β‐epi‐maytenfolic acid were isolated. The structure and stereochemistry of epikatonic acid were established by two‐dimensional NMR spectroscopi

## Abstract Structural studies in the solid state by X‐ray crystallography and by ^13^C and ^15^N CPMAS NMR spectroscopy carried out on a series of 2‐aminotroponimine derivatives **2**−**5** has allowed to establish the existence of hydrogen bonding and to determine the most stable tautomer. Almost
The structure of N-formyl, N-acetyI-N-methyl, and N-acetyl glycosylamines has been studied by NMR spectroscopy in solution, single crystal X-ray diffractometry, and corroborated by PM3 semiempirical calculations. The results quite agree with an anti conformation around the glycosydic bond for these
