An efficient method for the N-arylation of primary and some secondary amines using 2-halocyclohex-2-enones in an aliphatic-to-aromatictransformation in the presence of a substoichiometric amount of pTsOH has been developed.

describe the totalsynthesis of methylene‐bridged biscarbazole alkaloids by using a late‐stage Ullmann‐type coupling of fully functionalised carbazole subunits. The carbazole derivatives were synthesised via a sequence of palladium(0)‐ and palladium(II)‐catalysed coupling reactions. Our approach has provided bismurrayafoline‐A, bismurrayafolinol, chrestifolines B–D, and the firsttotalsynthesis of murrastifoline‐C
