TL;DR: The practical syntheses of 1,14-diaza[5]helicene (1), 1-aza[6]he Licene (2), and 2-aza [6] helicenes (3) are reported, which have succeeded in resolving racemates of 2 and 3 into their enantiomers, assigning their absolute configuration, determining the energy barriers to racemization, and obtaining Xray structures of their corresponding silver complexes.

TL;DR: A nonphotochemical synthetic route to 3-hexahelicenol is reported that involves a key [2+2-2] cycloisomerization of CH(3)O-substituted triyne that is readily available from 1-methoxy-3-methylbenzene and 1-bromo-2-(bromomethyl)naphthalene.

TL;DR: In this article, a nonphotochemical methodology was proposed for enantioselective synthesis of a helical skeleton employing the Ni(cod) 2 /(S)-(−)-MOP catalytic system.

TL;DR: An original approach to helicene frameworks exploiting atom economic isomerization of appropriate energy-rich aromatic cis,cis-dienetriynes has been developed and can be adapted to prepare functionalized helicenes as exemplified by the eight-step synthesis of 7,8-dibutyl-2,3-dimethoxy[6]helicene.

TL;DR: The simplicity of this non-photochemical approach combined with the potential for helicity control favors dibenzohelicenes over the parent helicenes for practical applications.
