hexahydropyrrolo[3,4-b]carbazol-1-ones, hexahydrofuro[3,4-b]carbazol-3-ones and hexahydropyrrolo[3,4-b]carbazol-3-ones were synthesized in 59% to 62% yields by domino Wittig Diels― Alder reactions from indole-3-carboxaldehyde and indole-2-carboxaldehyde and Wittig reagents. Further the corresponding carbazolelactones and carbazolelactams were obtained by oxidation with DDQ.
