experimental part, p. 3582 - 3591 (2009/09/08)
Interaction of 2/(3)-methyl-3/(2)-vinylindoles and DMF·DMA/DMA·DMA at 110 °C led to the in situ generation of enamines, which on concurrent electrocyclization followed by subsequent aromatization afforded substituted carbazoles.

A new route for the synthesis of carbazoles has been realized through the intermediacy of 2,3-divinylindoles involving an electrocyclization followed by aromatization.
84. Thermal 1,6-electrocyclization reactions of acceptor-substituted 2,3-divinyl-1H-indoles yielding functionalized carbazoles

, p. 827 - 838 (2007/10/02)
Three new synthetic procedures for and thermal 1,6-electrocyclizations of acceptor-substituted 2,3-divinyl-1H-indoles leading to functionalized carbazoles are described. The scope and limitations as well as some mechanistic aspects of the methodologies are discussed. The key strategies employed include Pd(II)-catalyzed coupling and Wittig procedures.
1,6-ELECTROCYCLIZATION REACTIONS OF ACCEPTOR-SUBSTITUTED 2,3-DIVINYLINDOLES TO FUNCTIONALIZED CARBAZOLES

, p. 587 - 592 (2007/10/02)
The syntheses and thermal 1,6-electrocyclization reactions of acceptor-substituted 2,3-divinylindoles, which give rise to functionalized carbazole derivatives, are described.
