Disclosed is a method for producing an ester or lactone in which a secondary alcohol represented by following Formula (1) (wherein Ra and Rb each represent an organic group, or Ra and Rb may be combined to form a ring together with the adjacent carbon atom) is oxidized by molecular oxygen in the presence of a nitrogen-containing cyclic compound containing a structure represented by following Formula (I) [wherein X represents an oxygen atom or an -OR group (wherein R represents a hydrogen atom or hydroxyl-protecting group)] as a constituent of its ring, and at least one of a fluorine-containing alcohol and a fluorinated sulfonic acid, and thereby yields a compound represented by following Formula (2):
本发明公开了一种生产酯或内酯的方法,在该方法中,由下式(1)代表的仲醇(其中 Ra 和 Rb 各代表一个有机基团、其中 X 代表氧原子或-OR 基团(其中 R 代表氢原子或羟基保护基团)]作为其环的组成成分的含氮环状化合物以及含氟醇和氟化磺酸中的至少一种存在的情况下被分子氧氧化,从而得到下式(2)所代表的化合物:
