The synthesis of methyl (−)-shikimate [(−)-2] was achieved via lipase-catalyzed optical resolution of (1S*,4R*,5R*)-4-hydroxy-6-oxabicyclo[3.2.1]oct-2-en-7-one (3). Transesterification of (±)-3 and vinyl acetate with lipase MY and subsequent hydrolysis gave optically pure (−)-3. This compound was converted to (−)-2 in two steps.
通过脂肪酶催化光学分解 (1S*,4R*,5R*)-4-羟基-6-氧杂双环[3.2.1]辛-2-烯-7-酮 (3),合成了(-)-莽草酸甲酯[(-)-2]。用脂肪酶 MY 对 (±)-3 和乙酸乙烯酯进行酯交换反应,然后进行水解,得到光学纯度为 (-)-3 的化合物。该化合物分两步转化为 (-)-2。
