The synthesis of 3,4-diaryl-3-pyrrolin-2-ones and 4-aryl-3-pyrrolin-2-ones using Suzuki–Miyaura cross-coupling reactions of tetramicacidsulfonates with arylboronic acids has been studied. The effect that sulfonateester, sterics, and lactamprotection has on the cross-coupling reaction was evaluated. As expected, triflates were better cross-coupling partners than the corresponding tosylates. The
