A new intramolecularoxy-cyclization of 2-alkenylbenzamides catalyzed by ArI has been developed. This protocol is highlighted by its metal-free catalytic system and extremely short reaction time, providing efficient and straightforward access to various benzoiminolactones in good to excellent yields. Interestingly, a regioselective transformation occurred when using two different reaction systems. Mechanistic studies suggested thatmCPBA acts as both oxidant and ligand at the IIIIcenter, and the Lewis acid BF3accelerated ligand exchange and reductive elimination in the catalytic process.

An intramolecular hydroamidation of ortho-vinyl benzamides had been developed. The reaction was promoted efficiently by potassium tert-butoxide and N,N-dimethylformamide without the need for strong oxidants or transition-metal catalysts. A series of dihyd

A series of diversely substituted 2H-2-benzazepine-1,3-diones were efficiently prepared from the unsaturated precursors, N-acyl-o-vinylbenzamides, through a ring-closing metathesis reaction. The parent compounds were easily obtained from the appropriate o

A variety of diversely substituted isoindeno[1,2-c]isoquinolin-5,11-diones has been readily assembled through a sequence involving a Suzuki-Miyaura cross-coupling reaction with enol phosphates combined with a ring-closing metathesis (RCM) reaction. Intram
