Novel, chiral Lewis base organocatalysts, which displayed poor enantioselection in the hydrosilylation of N‐aryl β‐enamino esters, were found to be the catalysts of choice in the hydrosilylation of α‐imino esters. In the presence of 10 mol‐% of the best catalyst, various α‐imino esters underwent enantioselective hydrosilylation to provide a wide range of chiral α‐amino esters with good yields (up to 97 %) and high enantioselectivities (up to 93 % ee) except for some special substrates.
