A Novel Pseudotwistane, Pulchellon from Gaillardia pulchella
スポンサーリンク
概要
- 論文の詳細を見る
A novel pseudotwistane named pulchellon was first isolated from a collection of Gaillardia pulchella as a minor constituent along with the pseudoguianolide alkaloids, pulchellidine and neopulchellidine. The absolute stereostructure of pulchellon (I) as designated in Fig. 6 has been completely established on the basis of its chemical and spectral evidences together with the biogenetic consideration as well as the direct X-ray crystallographic analysis of pulchellon. A possible biogenetic pathway of I through the keto key intermediate (VII) derived from another constituent pulchellin (III) has also been proposed.
