The mechanisms of Cp*Rh(OAc) 2 ‐catalyzed coupling reaction of N‐methoxybenzamide with alkyl‐terminated enyne have been investigated using density functional theory (DFT) calculations. With the addition of NaOAc, the product transforms from lactam P1 in reaction A to iminolactone P2 in reaction B due to the formed stable OAc − coordinated intermediate. The electronic effect accounts for the observed chemooselectivity in reaction B.
