Endiandric acid, a novel carboxylic acid from Endiandra introrsa(Lauraceae): X-ray structure determination

Abstract
X-Ray crystal structure analysis shows that endiandric acid, a constituent of the Australian tree Endiandra introrsa, has the novel racemic structure (1), (1RS,3RS,6SR,7SR,10SR,11RS,12RS,13RS)-(6-phenyltetracyclo[5.4.2.03,13010,12]trideca-4,8-dien-11-yl]acetic acid.
