Structurally unique C28 terpenoids, perovsfolins A (1) and B (2), were isolated from the aerial parts of an Uzbek medicinal plant, Perovskia scrophulariifolia (Lamiaceae). Their chemical structures including an unprecedented 6/8/6/6/6 pentacyclic carbon skeleton with a C6-C3 ester moiety were elucidated on the basis of spectroscopic analyses aided by density functional theory calculations as well as chemical evidence. Perovsfolin B (2) exhibited an anti-neuroinflammatory activity.

An asymmetric synthesis of (+)-salvianolic acid A with cardioprotective properties, has been accomplished in a convergent manner in eight steps and 10.6% overall yield. This synthesis features an asymmetric addition of organometallics to optically pure 2,3-epoxypropionate in the presence of BF3·Et2O, Ru(III)-catalyzed directed [Formula presented] olefination, and I2-catalyzed isomerization reaction.
