The invention provides a synthetic method of (purin-6-yl)amino acids which are useful as medicaments of anticancer, anti-virus agents and so on or their intermediates. Methyl (R, S)-3-[4-(9-benzylpurin-6-yl) phenyl]-2-[ (t-butoxycarbonyl) amino] propanoate is produced by making 9-benzyl-6-iodopurine react with methyl (R, S)-2-[ (t-butoxycarbonyl) amino]-3-[4-(trimethylstananyl) phenyl] propionate in the presence of Pd2dba3, triphenylarsine and copper iodide.

Intermolecular Hydrogen Abstraction Reaction between Nitrogen Radicals in Purine Rings and Alkyl Ethers: A Highly Selective Method for the Synthesis of N-9 Alkylated Purine Nucleoside Derivatives
A highly selective method for the synthesis of N‐9 alkylated purine nucleoside derivatives via an intermolecular hydrogen abstraction reaction between nitrogen radicals in purine rings and alkyl ethers was developed. Novel purine nucleoside derivatives were obtained with good to high yields in the presence of (diacetoxyiodo)benzene (DIB) and iodine in one‐step reaction.
