Synthesis of Phenanthrenes and Polycyclic Heteroarenes by Transition‐Metal Catalyzed Cycloisomerization Reactions
TL;DR: The scope of this novel method for the preparation of polycyclic arenes is illustrated by thetotal synthesis of a series of polyoxygenated phenanthrenes that are close relatives of the anticancer agent combretastatin A-4, as well as by the total synthesis of the aporphine alkaloid O-methyl-dehydroisopiline and its naturally occurring symmetrical dimer.

Stilbene oligomers from Parthenocissus laetevirens: isolation, biomimetic synthesis, absolute configuration, and implication of antioxidative defense system in the plant.
TL;DR: The results showed that stilbene oligomers with an unusual phenanthrene moiety exhibited much stronger antioxidant activities, which was hypothesized to play a role in the antioxidative defense system of the plant.

The Constituents of Eucommia ulmoides OLIV. I. Isolation of (+)-Medioresinol Di-O-β-D-glucopyranoside
TL;DR: In this paper, a new lignan diglycoside was isolated from the bark of Eucommia ulmoides OLIV. (Eucommiaceae) and its structure was established as (+)-medioresinol di-O-β-D-glucopyranoside (1) by means of chemical and spectral studies.
