We present kinetic modeling results in order to evaluate different mechanistic proposals that have been presented concerning the role of “downstream intermediates” in enamine catalysis. The focus of the debate is the identity and role of aminal intermediates. Are the aminals syn or are they anti, or are both observed? Do they lie on the catalytic cycle, as we suggest, or are they off-cycle species?
