Stereoselective total syntheses of natural (+)-varitriol (1), (−)-varitriol (2), 5′-epi-(+)-varitriol (3), and 4′-epi-(−)-varitriol (4) have been accomplished with use of d-mannitol as a chiral pool material. The Heck reaction was used to assemble the olefinic sugar moiety and the aromatic triflate moiety.
立体选择性全合成天然(+)-曲三醇(1),(-)-曲三醇(2),5'- Epi -(+)-曲三醇(3)和4'- epi -(-)-曲三醇(4)已经通过使用d-甘露糖醇作为手性库材料来完成。使用Heck反应组装烯烃糖部分和芳族三氟甲磺酸酯部分。
