Ginkgolide B—A Complex Organic Compound from the Ginkgo Tree 

Hydrogen atoms bonded to ring carbons are omitted in the structure of ginkgolide B, a convention described in Section 1.7. 

In 1932 ginkgolide B was one of four components isolated from ginkgo extracts, and its stracture was determined in 1967. Although its rigid ring system of 20 carbons contained in a compact three-dimensional shape made it a challenging molecule to prepare in the laboratory. Professor E. J. Corey and co-workers at Harvard University reported the synthesis of ginkgolide B in the laboratory in 1988.
