Treatment of carboxylicacids with borontrichloride followed by addition of alcohol provides the carboxylicester. This esterification, following BCl3 ether or ester OC cleavage reaction conditions, proceeds cleanly in good yields with most substrates. Cleavage of benzyl esters with borontrichloride then treating with methanol affords the methyl ester.
