Abstract
In methyl y-8-isopropyl-5-methyl-9-oxotricyclo[9.3.00(5,10)] tetradeca -1,7-diene-10-carboxylate, C20H25BrO4, the seven-membered ring is half -chair shaped, the six-membered ring adopts a boat conformation and th e five-membered rings both adopt envelope conformations. The molecule adopts an overall hemispherical conformation.
