An unexpected modulation of the chemoselectivity in the Michael–Dieckmann type reactions of 2-acylaminoacrylates with ketenediethylacetal is observed, depending on the nature of the acylamino group. Experimental and theoretical studies are presented to offer insights into the origin of this substituent effect in terms of a polar stepwise mechanism.
