Synthesis and Helical Structure of Oligo(quinoline-2,3-diyl)s

Abstract

Abstract Oligo(quinoline-2,3-diyl)s having a terminal bromo group were synthesized by the Suzuki–Miyaura coupling of 5,8-disubstituted 2-bromoquinolin-3-ylboronic acid derivatives, and their helical structures were elucidated by a single-crystal X-ray analysis of the hexamer, UV measurements, and induction of a non-racemic helical sense by introduction of a chiral end group.
