  The metalation-silylation of O-trimethylsilyl aldehyde cyanohydrins

  摘要：

  The metalation-trimethylsilyation of O-trimethylsilyl (saturated) aldehyde cyanohydrins was achieved by in situ treatment with LDA and trimethylchlorosilane at -78-degrees-C. C-Silyl products (O-trimethylsilyl acylsilane cyanohydrins) generally predominated, but N-silyl derivatives (ketenimines) were found in some instances. LDA could be added across the C = N bond of the latter. The metalation-trimethylsilylation of O-trimethylsilyl benzaldehyde cyanohydrin could only be effected if 2 equiv of trimethylchlorosilane were employed per equivalent of cyanohydrin anion.

  A new hydroxynitrile lyase (HNL) was isolated from the seed of Japanese apricot (Prunus mume). The enzyme has similar properties with HNL isolated from other Prunus species and is FAD containing enzyme. It accepts a large number of unnatural substrates (benzaldehyde and its variant) for the addition of HCN to produce the corresponding cyanohydrins in excellent optical and chemical yields. A new HPLC

  从日本杏（Prunus mume）的种子中分离出一种新的羟腈裂解酶（HNL ）。该酶与从其他李属物种中分离的HNL具有相似的特性，并且是含FAD的酶。它接受大量非天然底物（苯甲醛及其变体）以添加HCN，从而以优异的光学和化学收率生产相应的氰醇。针对该酶开发了一种新的基于HPLC的对映选择性测定技术，该技术可促进在缓冲溶液（pH = 4.5）中将KCN添加到苯甲醛中。
