Abstract

The first synthesis of 6,11-diamino-[6]carbohelicenes is described: the short 5 step sequence involves Suzuki–Miyaura coupling, functional group transformations and electrophilic aromatic cyclisation; the original strategy allows the preparation of di- and tetra-substituted helicenes in comfortable yields.
