Spiraling up : Easy access to dibenzo[5]‐, dibenzo[6]‐, and dibenzo[7]helicenes (see picture) as well as their functionalized derivatives includes Sonogashira and Suzuki–Miyaura couplings, desilylation, and [2+2+2] alkyne cycloisomerization. The simplicity of this non‐photochemical approach combined with the potential for helicity control favors dibenzohelicenes over the parent helicenes for practical applications.
