Abstract
Abstract Five‐membered carbocycles are ubiquitously found in natural products, pharmaceuticals, and other classes of organic compounds. Within this category, cyclopentenes deserve special attention due to their prevalence as targets and as well as key intermediates for synthesizing more complex molecules. Herein, we offer an overview summarizing some significant recent advances in the catalytic assembly of this structural motif. A great variety of synthetic methodologies and strategies are covered, including transition metal‐catalyzed or organocatalyzed processes. Both inter‐ and intramolecular transformations are documented. On this ground, our expertise in the application of C−H functionalization reactions oriented towards the formation of this ring and its subsequent selective functionalization is embedded.
