Crystallization-induced dynamic resolution
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 … WebDynamic atropselective resolutions of the peptide – biphenyl hybrids 3–5 were achieved by crystallization from methanol solution. These compounds were studied by single-crystal X-ray diffraction.These hybrids crystallize in highly ordered structures kept by an extensive array of intramolecular and intermolecular hydrogen bonds.
