WebDynamic atroposelective resolutions in mixed Cu(II) complexes derived from stereolabile biphenyl-2,2′-diol and enantiopure 1,2-diamines have been achieved by crystallization. In these cases, all 2,2′-disubstituted biphenyl fragments in the crystal have the same configuration at the stereogenic axis as a result of the transmission of chirality at the … WebMar 23, 2024 · A highly efficient asymmetric synthesis of the IDO inhibitor navoximod, featuring the stereoselective installation of two relative and two absolute stereocenters from an advanced racemic intermediate, is described. The stereocenters were set via a crystallization-induced dynamic resolution along with two selective ketone …
