A reaction scheme showing two continuous flow Mallory cyclisations to form thieno[6]helicenes. Caption text: Scheme 3: Mallory photocyclization of thieno[4]helicene stilbenes 3a and 3b to afford thieno[6]helicenes 4a and 4b.
A reaction table showing azahelicenes. The caption reads: Table 2: Scope of the Mallory photocyclisation with catalytic iodine. *65°C, 180 s residence time. reference a) Biet et al. (2017)
A table of [4]- to [7]heterohelicenes produced by the continuous flow photocyclisation. The caption reads: Table 1: Scope of the Mallory photocyclisation with stoichiometric iodine. * Concentration of reaction diluted to (0.5 mM). **Solvent was a 1:1 Toluene:MeCN mixture. reference a) Iwao et al. (1980).
A reaction scheme showing a three step conversion of a thiophene-naphthyl stilbene to a bis(thieno)[6]helicene.
