Amidoalkylation of Pyrazine-2,3-dicarbonitrile by the Radical Generated from N-Alkanoylanilinoalkanoic Acid
摘要:
N-Alkanoylanilinoacetic acid and 2-N-alkanoylanilinopropionic acid gave N-alkanoylanilinomethyl radical and 1-N-alkanoylanilinoethyl radical respectively by the peroxodisulfate oxidation catalized by silver ion. The former radical reacts with pyrazine-2,3-dicarbonitrile to give both monosubstitution product (6) and disubstitution product (7), whereas the latter radical gives only monosubstitution product due to the steric hindrance for the second radical substitution.
