A general synthetic approach to diterpenoids of the cis-clerodane family has been developed, culminating in the first total synthesis, in racemic form, of ({\pm})-6β-acetoxy-2-oxokolavenool (85) and ({\pm})-2-oxo-5α ,8α-13,14,15,16-tetranorclerod-3-en-12-oic acid (86). The key o…

Six new compounds were isolated from the aerial and root parts of S. viridis L. cv. Blue Jeans. Two new triterpenoids, lup-20(29)-ene-2α-acetate-3β-ol, and lup-20(29)-ene-2α-ol-3β-acetate were found in the aerial part together with lup-20(29)-ene-2α-3β-diol, ursolic acid, oleano…
