摘要

Abstract 2-Amino-5-(p-hydroxyphenyl)-1, 4-pyrazine and 2-amino-3, 5-bis (p-hydroxyphenyl)- 1, 4-pyrazine are endowed with excellent antioxidative properties. For a possible development in medicinal chemistry, the lipophilicity of these lead compounds has to be increased. Therefore various methods of N-alkylation were systematically explored. The best results were obtained by quenching aminopyrazinyl anion with alkyl iodides, and by ...
