Several new β-amino esters were prepared in two simple steps from β-keto ester derivatives and primary and secondary amines under mild conditions. The hydrogenation of various enamino esters was performed at 50 ËC in the presence of iridium catalysts. The new β-N-substituted amino esters were isolated in high yields.
