Flexible synthesis of diverse N-heterocycles from substrates attainable from biomass†
Abstract
A suite of diverse N-heterocycles including dihydroindolone, indole, dihydroindolizinone, 2-pyridone, pyrido[1,2-a]indole, dihydrocarbazolone and carbazole have all been prepared from dimethyl itaconate and pyrrole, two compounds attainable from biomass.
