  By a chemo-enzymatic approach we performed a large-scale, stereoselective synthesis of the Cα-methylated α-hydroxy acid L-(αMe)Hyv. We also prepared model depsipeptides based on this sterically demanding residue in combination with the α-amino acids L-Ala, L-Val, and Aib. From solution (FT-IR absorption and 1H NMR) and crystal-state (X-ray diffraction) conformational analyses we found that L-(αMe)Hyv forces depsipeptides to fold into right-handed β-turn/helical structures by analogy with the reported propensity of L-(αMe)Val, its α-amino acid counterpart.

  通过化学酶法，我们进行了Cα-甲基化α-羟基酸L-(αMe)Hyv 的大规模、立体选择性合成。我们还根据这种空间要求残基与α-氨基酸L-Ala、L-Val 和Aib 的组合制备了缩酚肽模型。通过溶液（FT-IR 吸收和 1H NMR）和晶态（X 射线衍射）构象分析，我们发现 L-(αMe)Hyv 迫使缩酚肽通过类比折叠成右手β-转/螺旋结构与报道的L-(αMe)Val（其α-氨基酸对应物）的倾向有关。

  A straightforward process for the encapsulation of HbHNL under low methanol conditions has been developed. By adding a sol, prepared by hydrolysis of TMOS/MTMS at pH 2.8 with continuous removal of methanol, to a stirred solution of the enzyme in a buffer at pH 6.5, at least 65% of the activity of the free enzyme could be recovered after the encapsulation. The aquagels were successfully used in the synthesis of (S)-cyanohydrins. (C) 2004 Elsevier Ltd. All rights reserved.

  (R)-Ketone-cyanohydrins (R)-2 are obtained with high enantioselectivity from aliphatic ketones 1 and HCN in organic solvents using (R)-oxynitrilase (EC 4.1.2.10) as catalyst. Acid catalyzed hydrolysis of the cyanohydrins (R)-2 affords the corresponding (R)-alpha-hydroxy-alpha-methyl-carboxylic acids (R)-3 without measurable racemization.
