Abstract
A seemingly minor change to a reactant is shown to cause a change in reaction mechanisms. Conjugate addition of organocopper reagents to bicyclic α,β-unsaturated lactams derived from pyroglutaminol is determined by the nature of the aminal group. Aminals derived from aldehydes give anti addition; those from ketones give syn addition. Divergence in diastereoselection occurs because the substrates react by different mechanisms, ultimately due to a small but significant difference in pyramidalization of the aminal nitrogen.

Abstract
A simple synthesis of N-aryl-3-aminodihydropyrrol-2-one-4-carboxylates via one-pot multi-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of oxalic acid dihydrate (20 mol%) as catalyst in methanol is described. This homogeneous catalytic procedure offers advantages including mild reaction conditions, good to high yields, short reaction time, simple and readily available starting materials, easy work-up and there is no need for column chromatography.
