Title: Noncovalent Interactions in the Asymmetric Synthesis of Rigid, Conjugated Helical Structures

Journal Article · · Angew. Chem. Int. Ed.

Tetrakis({beta}-trithiophene) 1 folds into a helical conformation (RRR) that facilitates double ring annelation, with high diastereoselectivity and modest enantioselectivity, to provide bis[7]helicene 2 (MRM). This rigid, helically locked structure has enhanced chiroptical properties similar to the corresponding [15]helicene.
