Abstract
When 1-(2-isocyanophenyl)pyrrole was treated with a catalytic amount o f boron trifluoride, pyrrolo[1,2-a]quinoxaline nias obtained almost qu antitatively. The reaction in the presence of aldehydes or ketones gav e the corresponding 4-(1-hydroxyalkyl)pyrrolo[1,2-a]quinoxalines in mo derate to good isolated yields.
