Triphenylphosphine-Catalyzed, Novel, One-Pot, Multicomponent Synthesis of Functionalizedβ-Acetamido Carbonyls
摘要:
An efficient triphenylphosphine-catalyzed synthesis of beta-acetamido carbonyls via multicomponent reaction of aromatic aldehydes, enolizable ketones or beta-keto esters, acid chlorides and acetonitrile at room temperature is described. The process is remarkably simple, environmentally benign, and uses Lewis base for the first time in such type of reaction.
