The total synthesis of crassalactone A ( 1 ) has been achieved in twelve steps starting from commercially available 1,5‐D ‐gluconolactone. Still? Gennari olefination, one‐pot deprotection, and lactonization are the key reactions involved in the synthesis. 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

A stereoselective total synthesis of a naturally occurring cytotoxic styryl lactone, crassalactone A ( 1 ), has been accomplished. The synthesis involves (?)‐diisopropyl D ‐tartrate as the starting material, and the stereoselective additions of Grignard reagent and MeNO2 to two chiral aldehyde intermediates as the key steps. 相似文献
