Baeyer-Villiger氧化反应能控制产物的立体化学结构,在有机合成中对功能基转化和环扩张有重要的意义,因此氧化所得的产物可以广泛应用于合成许多天然产物和药物中间体以及一些高分子材料的单体等,是目前有机化学研究的热点之一。随着对该反应研究的深入,其催化剂的类型也在不断地增多,包括均相催化剂、非均相催化剂、生物催化剂。均相催化剂选择性和转化率虽高,但不及非均相催化剂重复利用率高。生物催化剂绿色环保,是未来研究的重点之一。本文从均相催化、非均相催化和生物催化三个方面对Baeyer-Villiger氧化反应相关的研究新进展进行了阐述,重点介绍了不同催化体系下催化剂与反应底物之间的作用,总结了有关催化反应的机理,并对Baeyer-Villiger氧化反应的发展进行了展望。

Baeyer-Villiger reaction can take control of the stereochemical structure of the product. It is significant in organic synthesis for the conversion of functional groups and ring expansion. The oxide product of Baeyer-Villiger reaction can be widely used in the synthesis of many natural products and pharmaceutical intermediates, as well as some polymer material monomer. With the further research on Baeyer-Villiger reaction, the types of catalysts are increasing continuously, including homogeneous catalysts, heterogeneous catalysts, biocatalysts. Homogeneous catalyst often brings excellent conversion rate and good selectivity, but has lower recycling rate than the heterogeneous catalyst. And the environmentally-friendly biocatalysts are still the focus of the study. In this review, we provide an overview of the latest achievements in Baeyer-Villiger reaction from the aspects of homogeneous catalysis, heterogeneous catalysis and biocatalysis, especially with an emphasis on the clarification of the relationship between catalysts and substrates in different catalyst systems. The mechanisms of the reaction are summarized in detail in the review. And the future advance of Baeyer-Villiger reaction is prospected.
