Studies on Pyrazine. 23. Homolytic Acylation of 2-Amino-3-cyanopyrazine and the Related Compounds with α-Keto Acids: A Synthesis of 5-Acyl-3-aminopyrazinecarboxylic Acid Derivatives
Homolytic acylation of 2-amino-3-cyanopyrazine (1) with α-keto acids led to the formation of 6-acetylated compounds in 74-85percent yields.Methyl 3-aminopyrazinecarboxylate (2) and 3-aminopyrazinecarboxamide (3) were also acylated under the same condition
