A highly atom-economical protocol for the synthesis of tetrasubstituted furans has been developed. This process is realized through the tandem reactions of Cs2CO3 promoted C-C σ-bond activation of α-aryl ketones followed by Zn-cataly

A novel ring expansion reaction of indene-1,3-dione with alkynyl ketones under transition-metal-free conditions has been developed. This process offers an efficient and direct way to synthesize benzoannulated seven-membered rings or fused-ring compounds t

Diarylalkynones were synthesized from one-pot Pd-catalyzed carbonylative and noncarbonylative coupling reactions of propiolic acid with aryl iodides under a carbon monoxide atmosphere. Aryl iodide (2.0 equiv), propiolic acid (1.0 equiv), Pd(PPh3)2Cl2 (5 mol %), CuCl (10 mol %), Et3N (6.0 equiv), and CO (8 atm) were reacted under optimized conditions in CH3CN at 80 °C for 1 h. This process afforded good yields and functional group tolerance.
