Carbon dioxide(CO2)is an abundant and renewable C1 feedstock for the synthesis of a variety of valuable chemicals.Thus,the development of novel and efficient methodologies for the chemical fixation of CO2 has become one of the most important research topics for chemists.Herein,we developed a copper-catalyzed coupling reaction of internal propargylic alcohols with CO2 in the presence of N,N-diisopropylethylamine,affording the corresponding α-alkylidene cyclic carbonates in moderate to excellent yields.More importantly,we have successfully developed a protocol for chemo-and stereoselective synthesis of a variety of(E)-α-iodoalkylidene cyclic carbonates.
