1. ChemInform Abstract: Regioselective Synthesis of Alkylpyrazines

Author: Jose Galindo and George Buechi
Subjects: chemistry.chemical_compound, chemistry, Stereochemistry, Methyl chloroformate, Potassium, Condensation, chemistry.chemical_element, Regioselectivity, Organic chemistry, General Medicine
Abstract: A new regioselective synthesis of alkylpyrazines begins with condensation of α-oximido carbonyl compounds with allylamines. The resulting imines are isomerized in the presence of potassium tert-butoxide to the corresponding 1-hydroxy-1,4-diazahexatrienes. Thermal electrocyclization-aromatization to pyrazines is best performed after O-acylation of the oximes with methyl chloroformate
