Since L-prolinamide was revealed to have high capacity to catalyze asymmetric aldol reaction, great advances have been made on the design of chiral amino amide catalysts and their applications in asymmetric catalysis. In particular, the “enamine-double hydrogen-bonding activation mode” has turned out to be a general concept for the proliferation of structurally diverse range of organocatalysts. This review mainly describes asymmetric reactions catalyzed by chiral amino amides containing single hydrogen-bonding donor, double hydrogen-bonding donors and multiple hydrogen-bonding donors, including enantioselective direct aldol reaction, Mannich reaction, Michael addition reaction, cycloaddition reaction, tandem cyclization reaction, Biginelli reaction and others.
