Palladium(ii)-catalysed total synthesis of naturally occurring pyrano[3,2-a]carbazole and pyrano[2,3-b]carbazole alkaloids

Hesse, Ronny,Jaeger, Anne,Schmidt, Arndt W.,Knoelker, Hans-Joachim

, p. 3866 - 3876 (2014/06/09)

Seven naturally occurring pyranocarbazole alkaloids (pyrayafoline A-E, O-methylmurrayamine A and O-methylmahanine) have been obtained by total synthesis using a palladium(ii)-catalysed oxidative cyclisation of a diarylamine to an orthogonally diprotected 2,7-dihydroxycarbazole as key step. This journal is the Partner Organisations 2014.
