Highly enantioselective synthesis of (2R)-α-(hydroxymethyl)glutamate (1), a selective agonist of mGluR2 and 3, was achieved in short steps using an asymmetric version of the Strecker synthesis. This was converted into its α-methoxymethyl- and α-benzyloxymethyl derivatives 2 and 3, possible ligands as tools to investigate glutamate receptors, via protection of the sterically hindered amino group by
使用Strecker合成的不对称形式,可以在短时间内实现对映体(2 R)-α-(羟甲基)谷氨酸(1)的高度对映选择性合成。通过相转移催化剂保护空间受阻的氨基,将其转化为其α-甲氧基甲基-和α-苄氧基甲基衍生物2和3,可能的配体作为研究谷氨酸受体的工具。
