Under the catalysis of Pd2(dba)3·CHCl3/(±)-L5 in THF at room temperature, the three-component decarboxylative coupling reactions among alkylidene pyrazolones, allyl carbonates and activemethylenecompounds proceeded readily and furnished the desired products in acceptable chemical yields. The chemical architecture of the obtained products was unambiguously confirmed by single crystal X-ray analysis
Under the catalysis of Pd(OAc)2/dppf/Na2CO3, the decarboxylative 1,4-addition reaction of benzofuran-based azadienes with allyl phenyl carbonates took place easily and delivered the desired products in reasonable chemical yields. The chemical structure of the target compounds was clearly identified by single crystal X-ray structural analysis.
