C1 Functionalization of Imidazo Heterocycles Carbon Dioxide Fixation

Utilizing CO as a one-carbon building block in the preparation of high-value chemical entities is a cornerstone of modern organic synthesis. Herein, we exemplify this strategy through a mild, one-pot methodology that gives rapid access to N-heteroaryl substituted 6-, 8- and 9-membered carbamates CO fixation.
