Article abstract of DOI:10.1055/s-1997-746

A novel approach to ellipticine derivatives is described. The palladium catalysed cross-coupling reaction of indolylborate 1 with vinylbromides 4 gives hexatrienes 5, which are subsequently converted to pyrido[4,3-b]carbazoles. In addition, the acid promoted spiroannelation reaction of hexatrienes 5 is observed to give spiroindoles 9.
