A simple, three‐step chemoenzymatic synthesis of L‐threo‐3‐benzyloxyaspartate (L‐TBOA), as well as L‐TBOA derivatives with F, CF3, and CH3 substituents at the aromatic ring, starting from dimethyl acetylenedicarboxylate was investigated. These chiral amino acids, which are extremely difficult to prepare by chemical synthesis, form an important class of inhibitors of excitatory amino acid transporters
一个简单的三步合成化学酶促大号-苏式-3- benzyloxyaspartate(大号-TBOA),以及大号带F,CF -TBOA衍生物3,和CH 3研究了从乙炔二羧酸二甲酯开始的芳香环上的取代基。这些通过化学合成极难制备的手性氨基酸形成了一类重要的兴奋性氨基酸转运蛋白抑制剂,涉及谷氨酸能神经传递的调节。此外,还探索了一种新的化学方法,用于合成TBOA及其衍生物的外消旋混合物。这些化学制备的外消旋体是手性HPLC中有价值的参考化合物,可用于建立相应的化学酶法制备的氨基酸的对映体纯度。
