Two methyl groups have been introduced into the positions α to the N-atom in 1,2,3,4,4a,5,6,7-octahydrobenzo [d]carbazoles in a ‘one-pot’ procedure; additionally bromination of 1H-2,3,4,4a-tetrahydro-6-isopropylcarbazoles has been shown to occur at C-8 and the derived bromides converted into 8-alkenylated derivatives as precursors of chain-breaking antioxidants of tuneable lipophilicity.
