Abstract

Being an abundant, easily available, and renewable one-carbon source, carbon dioxide has received much attention in organic synthesis. However, carbon dioxide is a thermodynamically inert molecule that is hard to incorporate into useful chemicals. Nevertheless, various elegant methods have been developed for the incorporation of carbon dioxide in a number of heterocycles. In this review, we summarize and update the recent advances in n-dig-cyclization of alkynes involving the fixation of CO2, including the 5-dig- and 6-dig-cyclization of alkynes.
