Nonracemic N-(2-aminopurin-6-yl)-substituted amino acids were synthesized by nucleophilic substitution of chlorine atom in 2-acetamido-6-chloropurine upon treatment with amino acid tert-butyl esters and subsequent removal of protecting groups. Their enantiomeric composition was determined by HPLC on chiral stationary phases.
非外消旋 N-(2-aminopurin-6-yl)-取代的氨基酸是通过在 2-acetamido-6-chloropurine 中用氨基酸叔丁酯处理并随后去除保护基团中的氯原子的亲核取代来合成的。它们的对映体组成通过手性固定相上的 HPLC 测定。
