Radical cyclisation reactions with indoles

Flanagan, S. R., Harrowven, D. C. and Bradley, M. (2003) Radical cyclisation reactions with indoles Tetrahedron Letters, 44, (9), pp. 1795-1798. (doi:10.1016/S0040-4039(03)00094-7).

Record type: Article


Several radical cyclisation reactions involving indoles are described. Most notably, we have shown that radical additions to C3 of an indole are frequently facile. A dichotomy in the course of radical cyclisation reactions to C2 of the indole has also been exposed wherein 6-endo-trig cyclisations are propagated by the loss of a hydrogen atom from C2 while 5-exo-trig cyclisations are propagated by hydrogen atom abstraction at C3 from tributyltin hydride. Cyclisations involving the addition of indolyl radical intermediates to arenes have also been demonstrated.
