Dec 23, 2015 · the design of the aryne precursors, the choice of oxazoline and the reaction conditions were key to accessing the desired, highly substituted, atropisomerically enriched. We report the preparation of axially stereoenriched biphenyls by the coupling of in situ generated aryllithiums and arynes using chiral oxazoline auxiliaries. The design of the aryne precursors,. Jul 17, 2024 · a highly efficient biocatalytic route for the atroposelective synthesis of biaryls by dynamic kinetic resolution (dkr) was developed. This dkr approach features a transient aza.
