Title:
NEW METHOD FOR ESTERIFYING CARBOXYLIC ACIDS
Document Type and Number:
Japanese Patent JP2006063035
Kind Code:
A
Abstract:
To provide an environment-conscious esterification method having conventional esterification function of a carboxylic acid and excellent atom economy.
The method for esterifying a carboxylic acid comprises bringing a carboxylic acid into contact with an alcohol and ditertiary butyl carbonate (Boc2O) in the presence of a catalytic amount of 1-tertiary-butoxy-2-tertiary-butoxycarbonyl-1,2-dihydroisoquinoline (BBDI) represented by formula (1) or isoquinoline.
