Steward, Kimberly M. published the artcileAsymmetric Synthesis of Diverse Glycolic Acid Scaffolds via Dynamic Kinetic Resolution of α-Keto Esters [Erratum to document cited in CA158:36961], Recommanded Product: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Journal of the American Chemical Society (2015), 137(11), 3991, database is CAplus and MEDLINE.
In follow up experiments the authors discovered errors in analyzing the unpurified 1H NMR spectra, which led to incorrect reporting of the crude diastereomer ratios for the lactone products; the correct ratios are given and an alternative exptl. procedure is presented that generally results in improved stereoselectivity.
