  The O-alkylation of carboxylic acids with diazo compounds provides a means to esterify carboxylic acids in aqueous solution. A Hammett analysis of the reactivity of diazo compounds derived from phenylglycinamide revealed that the (p-methylphenyl)glycinamide scaffold has an especially high reaction rate and ester/alcohol product ratio and esterifies protein carboxyl groups more efficiently than any known reagent.
• Biocatalytic reduction of α-keto amides to (R)-α-hydroxy amides using Candida parapsilosis ATCC 7330

  日期：2012.12

  Biocatalytic reduction of primary and secondary alpha-keto amides was accomplished using whole cells of Candida parapsilosis ATCC 7330. The primary (R)-alpha-hydroxy amides were obtained in good enantiomeric excess (up to 94%) and conversion (88-99%) as compared to the secondary (R)-alpha-hydroxy amides. (C) 2012 Elsevier B.V.
