Domino reactions - New concepts in the synthesis of indole alkaloids and other polycyclic indole derivatives

2-Vinylindoles, which are easily accessible via a domino process, are useful synthons for a variety of applications. Subsequent Diels-Alder reactions yield tetrahydrocarbazoles which can be dehydrated to carbazoles such as derivatives of olivacine or elipticine. Cycloadditions with enamine intermediates lead to the synthesis of epidasycarpidone.
