The first enantiopure 4,4â²-bipyridyls, 6, 8, and 9 have been prepared in four or five steps via bacterial dioxygenase-catalysed cis-dihydroxylation of 4-chloroquinoline1 and CâC coupling; ligands 6 and 9 are found to be effective building blocks for the preparation of chiral metalâorganic frameworks as demonstrated with the rational synthesis of two pillared-grid structures [Zn2(fumarate)2(L)], which exhibit interesting structural and dynamic aspects.
