A practical method for the direct preparation of diphenylmethyl (DPM) esters from 2-diphenylmethoxypyridine is described. The reaction was readily performed in the presence of a catalytic amount of boron trifluoride-diethyl etherate at room temperature. Using this reaction protocol, various carboxylic acids were converted to DPM esters with high yields. This method is highly effective for the protection
描述了一种由2-二苯基甲氧基吡啶直接制备二苯基甲基(DPM)酯的实用方法。该反应在室温下在催化量的三氟化硼-二乙基醚化物的存在下容易地进行。使用该反应方案,可以将各种羧酸高产率地转化为DPM酯。该方法对于保护羧酸和DPM酯的合成非常有效,并且为各种羧酸的简便酯化提供了一种有希望的方法。
