An efficient and stereodefined strategy is described for the asymmetric synthesis of a new styryllactone from the stem bark of Goniothalamus cardiopetalus, cardiobutanolide. The synthetic process is based on requisite manipulation of the functionalized bicyclic lactol-lactone intermediate incorporating the glucuronolactone-derived skeleton in a complete stereoselective manner. 相似文献

The first stereoselective total synthesis of the natural cryptopyranmoscatone B1 has been accomplished from 3,4,6-tri-O-acetyl-d-glucal. In addition to the double cross-metathesis reaction, a tandem nucleophilic addition-diastereoselective reduction of an in situ generated oxocarbenium cation have been used as key steps to assemble the glycoside moiety of the target molecule. 相似文献

The concise and efficient synthesis of (+)-goniofufurone, (+)-7-epi-goniofufurone, (+)-crassalactones B and C were achieved in 6 to 7 steps from the known d-glucono-δ-lactone derivative 9. An acid-mediated cascade cyclization was employed to construct the furanofurone bicyclic framework in one-pot. 相似文献
