A highly sustainable route to pyrrolidonederivatives - direct access to new biosourced solvents

Abstract

International audienceAccess to a series of 5-methylpyrrolidone derivatives is described directly using the biosourced levulinic acid in the absence of any additive, catalyst or solvent. The highly selective reaction proceeds with an E-factor as low as 0.2. Products are recovered in very good yields after a simple distillation
