New method for producing lactone derivative |
| abstract |
(57) [Summary] [Object] To provide a method for efficiently producing a lactone derivative from a hydroxycarboxylic acid derivative under mild conditions. [Structure] When a lactone derivative is produced from a hydroxycarboxylic acid or a silyloxycarboxylic acid silyl ester derivative, a compound represented by the general formula (2) (R 4 CO) 2 O (2) (wherein R 4 has a substituent) A carboxylic acid anhydride represented by the formula (1), which represents an optionally substituted aryl group, is reacted in the presence of a catalytic amount of a cationic catalyst. |
