Abstract
Furo[2,3-c]pyrroles 1a-d and benzofuro[2,3-c]pyrroles 6a-e were synthesized. Diels-Alder reactions of 1b and 6b gave 1:2 cycloadduct 13 and 1:1 cycloadduct 20, respectively. Parent compound 17 of benzofuro[2,3-c]pyrrole ring system was trapped as N-tert-butoxycarbonyl derivative 18. Oxidative extrusion of the N-bridge in Diels-Alder adduct 20 gave dibenzofuran 22. © 1994.
