Abstract

The reactivity of N-benzyl- and N-cyclohexyl-2-benzoyl-3-phenylaziridines toward allenoates in supercritical carbon dioxide (scCO2) is described. The study led to the development of a sustainable and selective approach to pyrrole derivatives and gave a new insight into the mechanism involved in the process.
