  Enantioselective synthesis of 2-substituted 4-aminobutanoic acid (GABA) analogues via cyanomethylation of chiral enolates

  摘要：

  由溴乙腈对源自(4S,5R)-3-酰基-4-甲基-5-苯基-1,3-恶唑烷-2-酮的钠或锂烯醇盐进行的氰甲基化通常显示出良好的立体选择性；尽管3-(3-羧基丙酰)恶唑烷酮5d的反应特别不选择性，3-(戊-4-烯酰)和3-(3,4-二甲氧基氢桂皮酰)恶唑烷酮5e和5f被发现是5d的有效合成等价物。这些氰甲基化产物可以通过恶唑烷酮手性辅助剂的碱性水解，并随之对氰基进行氢化，转化为4-氨基丁酸（γ-氨基丁酸，GABA）的2-取代衍生物。

  Stereoselective synthesis of both enantiomers of N-Boc-α-aryl-γ-aminobutyric acids

  摘要：

  Esterification of racemic alpha-aryl-beta-cyanopropionic acid chlorides with either (R)- or (S)-N-phenylpantolactam as the chiral auxiliary in the presence of Et3N resulted in the predominant formation of (alphaR,3'R)- or (alphaS,3'S)-configured pantolactam cyano ester, respectively, in nearly quantitative yields with diastereomeric ratios of up to 93:7. Column chromatography of the diastereoenriched cyano esters, followed by hydrolysis of the resulting diastereopure cyano esters under essentially nonracemizing conditions gave enantiopure alpha-aryl-beta-cyanopropionic acids, which were readily converted in high yields into enantiopure (OER)- and (alphaS)-configured N-tert-butoxycarbonyl-alpha-aryl-gamma-aminobutyric acid (GABA) derivatives of potential biological interest.

  日期：——

  Cyanomethylation by bromoacetonitrile of sodium or lithium enolates derived from (4S,5R)-3-acyl-4-methyl-5-phenyl-1,3-oxazolidin-2-ones usually shows good stereoselectivity; although the reaction of 3-(3-carboxypropanoyl)oxazolidinone 5d is exceptionally unselective, the 3-(pent-4-enoyl)- and 3-(3,4-dimethoxyhydrocinnamoyl)oxazolidinones 5e and 5f are found to be effective synthetic equivalents of 5d. The cyanomethylation products can be converted into 2-substituted derivatives of 4-aminobutanoic acid (γ-aminobutyric acid, GABA) by the alkaline hydrolysis of the oxazolidinone chiral auxiliary followed by hydrogenation of the cyano group.
