- Abstract
A straightforward approach to an array of multiaryl-1 H-pyrrol-2(3 H)-ones featuring an α-diarylated all-carbon quaternary center was developed by using diarylethanones and primary amines as the raw materials. A complete mechanism involving a CuO/TEMPO-mediated multistep cascade process with an inherent delicate balance of substituent electronic effect is proposed. Moreover, this class of multiaryl β,γ-unsaturated γ-lactams demonstrates an intriguing aggregation-induced emission effect valuable for potential application in developing luminescent materials.
