Facile Regiocontrolled Synthesis of Trialkyl-Substituted Pyrazines
摘要:
alpha-Nitro ketones can be transformed selectively into trialkyl-substituted pyrazines via reaction with a-amino ketones using octyl viologen as an electron-transfer reagent. The new synthetic method, and the optimal reaction conditions that allow for the regiochemical control, are described.
