The synthesis of aza-β-lactams via tandem Petasis-Ugi multi-component condensation and 1,3-diisopropylcarbodiimide (DIC) condensation reaction

Abstract The synthetic utility of a tandem Petasis–Ugi multi-component condensation and 1,3-diisopropylcarbodiimide condensation reactions have been employed to efficiently prepare two to four-dimensional libraries of aza-β-lactams.
