Amino Acids 125-142 synemin Homo sapiens 70-73 25867051-2 2015 The method utilizes simple alpha-amino acids to deliver syn- and anti- selective isoindolinones with remarkably high enantioselectivity (up to >99% ee) in good to excellent yields and diastereomeric ratios. Amino Acids 27-44 synemin Homo sapiens 56-59 11856002-3 2002 Oxidation of the metal carbene moiety followed by basic hydrolysis of the esters afforded enantiomerically highly enriched syn,exo-3,4,5-trisubstituted prolines, whereas acidic hydrolysis of the same functional groups proceeded with epimerization at the alpha-amino acid center leading to anti,exo-3,4,5-trisubstituted prolines of very high enantiomeric purity as well. Amino Acids 254-270 synemin Homo sapiens 123-126 28763205-3 2017 Subsequent in situ enantioselective [2,3]-sigmatropic rearrangement catalyzed by the isothiourea benzotetramisole forms syn-alpha-amino acid derivatives with high diastereo- and enantioselectivity.
