The invention provides novel compounds having the general formula (I) wherein wherein R1, R2, R3, R4, R5, R6, R7, R3, R8, R9, R10, R11, R12 and R23 are as described herein, compositions including the compounds and methods of using the compounds.
pyrrolidine-catalyzed three-component reaction of azlactone, N,O-acetal and alcohol for the synthesis of α,β-diamino ester was reported. The N,O-acetal served as the imine equivalent to occur Mannich reaction with azlactone, and the in situ generated α-functionalized azlactone subsequently underwent a ring-opening process in the presence of alcohol. A series of α,β-diamino esters were obtained in 36–99% yields
