Nonracemic N-(2-aminopurin-6-yl)-substituted aminoacids were synthesized by nucleophilic substitution of chlorine atom in 2-acetamido-6-chloropurine upon treatment with aminoacid tert-butyl esters and subsequent removal of protecting groups. Their enantiomeric composition was determined by HPLC on chiral stationary phases.
