• 29Si and13C NMR spectra of trimethylsilylated amino acids

  The 29Si and 13C NMR chemical shifts are reported for trimethylsilyl derivatives of 25 amino acids, the majority of which occur naturally as protein constituents of foodstuffs. The 29Si chemical shifts in trimethylsilyl esters of amino acids roughly correlate linearly with the pK values of the parent amino acid. No such simple correlations were found for the shifts in the fully trimethylsilylated amino

  2-Iminoacetic acid or glycine imine is a proposed key intermediate in the reductive amination of glyoxylic acid. In contrast to well-known α-amino acids the compound class of α-imino acids is not much explored and not well-characterized. Glycine imine was prepared through photochemical denitrogenation of 2-azidoacetic acid, spectroscopically characterized, and its reactivity studied in aqueous solution

• Lipase-Catalyzed Enantiomeric Resolution of Ceramides
  作者：Mikio Bakke、Masahiro Takizawa、Takeshi Sugai、Hiromichi Ohta

  DOI：10.1021/jo980727u

  日期：1998.10.1

  Lipase-catalyzed enantiomeric kinetic resolution of ceramides related to C-16-sphinganine and C-18-sphingenine is described. Two hydroxy groups in readily available racemic N-stearoyl-erythro-C-16-sphinganine were acetylated, and several kinds of lipases were screened for the hydrolysis of this substrate. Among them, a Burkholderia cepacia lipase (SC lipase A, Sumitomo Chemical Co., Ltd.) showed the highest reactivity and enantioselectivity. The rate of hydrolysis and selectivity were greatly affected by some additives. Especially, the combined use of a detergent, Triton X-100, and the solid support, Florisil, for immobilization showed the highest enantioselectivity (E = ca. 170), although the reaction rate turned low. Introduction of a double bond into the substrate (N-stearoyl-erythro-C-18-sphingenine) also retarded the hydrolysis. By utilizing the preferential hydrolysis of the acetate on the primary hydroxy group, another advantageous feature of this enzyme-catalyzed reaction, the resulting product could directly be used as the glycosyl acceptor for cerebroside synthesis.
