A simple and stereoselective synthesis of 1,3,4,4a,5,5a,6, 11a-octahydro-5-tert-butyldimethylsiloxy-1-methoxycarbonyl-6-methyl-2H-pyrido[3, 2-b]carbazole (2) and analogues, which are precursors towards the quebrachidine group of alkaloids, is presented which relies on a linear tandem radical cyclisation.
