摘要：
1,3-Dipolar cycloaddition of munchnones (mesoionic 1,3-oxazolium-5-olates) 3 and 4 with 2- and 3-nitroindoles, 2-nitrobenzo[b]furan, and 3-nitrobenzo[b]thiophene affords the corresponding pyrrolo[3,4-b]indoles, benzo[b]furo[2,3-c]pyrroles, and benzo[b]thieno[2,3-c]pyrroles, respectively, in one operation in good to excellent yields.
