摘要

Methods for the protection of phenolic hydroxy functions usually involve formation of alkyl ethers or esters. Groups such as acety1, l pivolyl, 2 vinylcarboxy, 3 and fluoren-9-ylcarboxy4 are among the most commonly used carboxylic acid groups. Although sulphonyl esters show a far greater stability to acidic conditions, S they are not commonly used because of the difficulty in removing them. Long reaction times and strongly basic conditions are ...
