Process for preparation of chiral lactones

The present invention provides a novel process for the preparation of chiral lactone compounds. Compared with the prior art, the method of the present invention prepares lactone compounds with improved yield and selectivity, and more importantly, reduces the use amount of expensive chiral catalysts, and thus is more cost-effective. 本发明提供用于制备手性内酯化合物的新方法。与现有技术相比，本发明的方法以改进的产率和选择性制备内酯化合物，并且更重要的是，减少了昂贵的手性催化剂的使用量，因此更具成本效益。
