δ-癸内酯的合成研究

Study on the Synthesis of δDecalactone

以环戊酮、正戊醛为原料，经羟醛缩合、氢化和氧化等三步反应合成了δ-癸内酯，在羟醛缩合中，采用了相转移催化技术；在催化加氢反应中，选用了几种离子交换树脂载钯催化剂来代替通常使用的５％Ｐｄ-Ｃ催化剂，最后以６５．５％的总产率合成了δ-癸内酯。

The synthesis of δdecalactone from cyclopentanone and valeraldehyde was studied.There are three reaction steps:condensation,hydrogenation and BaeyerVilliger oxidation.In aldol condensation,the phase transfer catalysis(PTC) technology was used and ion exchange resin supported Pd catalysts were prepared and substituted for usually used PdC catalyst in hydrogenation.Total yield was about 65.6%.
