摘要

View all references ] Esterification is extensively employed for the protection and further manipulation of the carboxylic acid functional group as well as the synthesis of natural products. Thus esterification of carboxylic acids has been the subject of numerous accounts throughout the years owing to the fundamental importance of this synthetic transformation. Early methods called for heating the carboxylic acid in an alcoholic solvent under acid or base catalysis. Other ...
