We report the total synthesis of the racemlc /l -amyrin derivatives olean-13(18)-ene (XII) and l&r-olesn-12-ene (XIII) by a direct route, not involving relays. Trevious syntheses of fl -amyrin derivatives using natural materials as relays have been described4. Condensation of the Grignard derivativ

The 13C NMR spectra of some pentacyclic triterpenoids, 3~-acetoxy-ll-oxo-olean-12-ene-30-oic acid methyl ester, 3~-acetoxy-ll-oxo-olean-12-ene-29-oic acid methyl ester, the corresponding 11-desoxo methyl esters, 3~-acetoxy-ll-oxo-18cw-olean-l2-en-30-oic acid methyl ester and 3~-acetoxy-ll-oxo-18~-ol
## Abstract The ^13^C NMR spectral data of 18 eudesmane derivatives, mainly acids and esters of natural and synthetic origin, are reported, and the γ‐effect of the epoxide ring in two diastereoisomeric epoxy esters is discussed.
The carbon-13 chemical shifts of mono-and 1,3-disubstituted adamantanes are reported. The effects caused by the substituents are compared with those met in aliphatic and alicyclic compounds. It is shown that the 1,4-interactions have only minor importance in 1-substituted adamantanes. The influence
