5－羟甲基－5－壬烷基戊内酯的合成

Synthesis of 5-Hydroxymethy-5-nonyl-δ-valerolactone

以已二酸为原料，经六步反应合成了５－羟甲基－５－壬烷基戊内酯，在形成手性中心的关键反应步骤中使用了（３Ｓ，４Ｓ）－１－苄基－１－甲基－３，４－二羟基吡咯碘化铵作手性相转移催化剂。

Title compound has been synthesised from the adipic acid(sttarting material)in six steps,a chiral phase transfer catalyst(3S, 4S)-1-benzyl-l-methyl-3,4-pyrrolidindiolonium iodide(PTC ) was used to promote the asymmetric reactions in the key steps of forming chiral centers.
