  Synthesis of chiral α-amino acids

  摘要：

  A novel method for the synthesis of chiral alpha-amino acids has been developed where the acid functionality was constructed by oxidizing a hydroxymethyl group introduced by Evans' method in the alpha-position of an appropriate acid substrate and the amino part came from the amide of the original carboxyl group following a modified Hofmann rearrangement reaction.

  Addition of organometallic reagents to O-(1-phenylbutyl)benzyloxyacetaldoxime in the presence of boron trifluoride diethyl etherate is highly diastereoselective; the resulting hydroxylamines are readily converted into protected 1,2-aminoalcohols and 2-hydroxymethyl nitrogen heterocycles, including the iminosugar 1,4-dideoxy-1,4-imino-d-ribitol, in high enantiomeric excess.

  在硼氟酸二乙醚存在下，有机金属试剂与O-(1-苯基丁基)苄氧基乙醛肟的加成具有高度的非对映选择性；生成的羟胺可方便地转化为受到保护的1,2-氨基醇和2-羟甲基氮杂环化合物，其中包括高对映体纯度的1,4-二脱氧1,4-亚氨基-d-核糖醇。

  Addition of a range of organolithium and Grignard reagents to (E)-O-(1-phenylbutyl)benzyloxyacetaldoxime 1 in the presence of boron trifluoride diethyl etherate is highly diastereoselective. The resulting hydroxylamines undergo N-O bond cleavage upon treatment with zinc-acetic acid or molybdenum hexacarbonyl to give, after N-protection, protected 1,2-aminoalcohols 3 in high enantiomeric purity.

  在三氟化硼二乙基醚化物的存在下向（E）-O-（1-苯基丁基）苄氧基乙醛肟1中添加一系列有机锂和格氏试剂是高度非对映选择性的。在用锌-乙酸或六羰基钼处理后，所得羟胺经历NO键裂解，以在N-保护后得到高对映体纯度的被保护的1,2-氨基醇3。3a和3d的脱苄基作用分别得到N-Boc（R）-丙氨醇和（S）-苯丙氨醇。羟胺2还用作α-氨基酸前体，2i被转化为N-甲酰基-（R）-丙氨酰基-（S）-（4-溴）苯丙氨酸酯7，即天然二肽的N-末端二肽。1,2-氨基醇衍生物的多功能性可以通过将其转化为5-，通过闭环易位反应，高对映体过量的6-和7-元2-羟甲基氮杂环15-19。二氢吡咯15的进一步反应得到亚氨基糖1，4-二脱氧-1，4-亚氨基-D-核糖醇。
