The Molecular and Crystal Structures of Two Derivatives of a Sesterterpene, Ophiobolin D

スポンサーリンク

概要

• 論文の詳細を見る

• The structures of two derivatives of a sesterterpene, ophiobolin D, were determined by X-ray crystallographic analyses. The final R-factors were 0.09 for both compounds. On the basis of their stereo-structures, it is suggested that the compounds are formed by different types of transannular reaction in an eight-membered ring, i. e., a migration of a double bond and a cyclization to yield a novel ring system composed of four fused five-membered rings.
