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 ˚C in the presence of iridium
catalysts. The new β-N-substituted amino esters were isolated
in high yields.
