Abstract:

Regioisomeric hexahydrofuro[3,4-b]carbazol-1-ones, 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 percent to 62 percent 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.
