Reactions of 3-(tetrahydropyrid-4-yl)-indoles with dienophiles: New heterocyclic functionalized indoles and pyrido[c]annellated carbazoles

Article abstract of DOI:10.1016/S0040-4039(00)74326-7

First reactions of 3-(1,2,3,6-tetrahydropyrid-4-yl)-indoles 1 with a variety of carbo- and heterodienophiles are described. These reactions provide a new access to heterocyclic functionalized indoles and pyrido[c]annellated carbazoles, compounds of interest as potential antidepressive and antitumor active agents.
