Easy Synthesis of Functionalized Hetero[7]helicenes
Hetero[7]helicenebisquinones can be synthesized easily on a multigram scale by combining the silyl enol ethers of 3,6-diacetyldibenzofuran, 3,6-diacetyldibenzothiophene, and 3,6-diacetylcarbazole with p-benzoquinone. They can be resolved into their enantiomers by a procedure that had previously been...
