Pododacric acid

Pododacric acid (23), isolated from Podocarpus dacrydiodes and P. totara, was shown" to be 12,16,17-trihydroxyabieta-8,ll,13-trien-19-oicacid. This structure was confirmed by a partial synthesis of the tetra-O-methyl derivative from podo-carpic acid demethylation gave the parent acid.
