An enamine intermediate is believed to be the central feature of biological catalysts, such as aldolases and small molecule amine organocatalysts. Despite decades of investigation of naturally occurring aldolase enzymes and recent studies on designed aldolase antibodies and organocatalysts, direct structural observation of an enamine intermediate has proven to be rare ...
