TL;DR: The final identification of VIII and the structural elucidation of X were accomplished by preparation of IX and the methyl ester of X (XI) from methyl ent-kaurenoate (XII) by means of the double bond isomerization and the dye-sensitized photooxidation.
Abstract: 15α-Hydroxy-ent-kaur-16-en-19-oic acid (IX) (=grandifloric acid) and a new diterpene acid, 17-hydroxy-ent-kaur-15-en-19-oic acid (X) were isolated as the minor constituents from the roots of Aralia cordata THUNB. The final identification of IX and the structural elucidation of X were accomplished by preparation of IX and the methyl ester of X (XI) from methyl ent-kaurenoate (XII) by means of the double bond isomerization and the dye-sensitized photooxidation.

TL;DR: In this paper, the absolute structure of a bromine-containing derivative and some chemical reactions on teucvin and its derivatives was determined based on an X-ray analysis.
Abstract: On the basis of the results of an X-ray analysis on a bromine-containing derivative (5) and some chemical reactions on teucvin and its derivatives, the absolute structure of the natural product has been determined to be ent-(6R, 12R)-15,16-epoxy-19-nor-9,4-friedolabda-4,13(16),14-triene-18,6:20,12-diolactone (2).
