  摘要：

  在无溶剂条件下，在催化量的 H3PW12O40 存在下，不同类型的伯醇和仲醇在室温下有效地转化为其相应的甲氧基甲基 (MOM) 和乙氧基甲基 (EOM) 醚。通过这种方法实现了在酚类和叔醇存在下对伯醇和仲醇的选择性保护。在回流条件下，在乙醇中使用这种催化剂也可以将这些醚脱保护为它们的母体醇。我们还发现，在酚类和叔醚、甲基和苄基醚、酯和三甲基甲硅烷基醚的存在下，伯醚和仲 MOM 和 EOM 醚被这种催化剂选择性地脱保护。该方案的显着优点是产量高、反应时间短、易于处理、无毒、

  Résumé A simple, green and chemoselective method for methoxymethylation and ethoxymethylation of primary and secondary alcohols using a Lewis acidic room temperature ionic liquid, [C4mim][InCl4], as catalyst and reaction medium under ambient temperature, microwave and ultrasonic irradiations is reported. In this catalytic system, the corresponding MOM-and EOM-ethers are obtained in excellent yields and in short reaction times. Furthermore, this catalytic system was used for mild and efficient transformations of these protected alcohols to their corresponding acetates and trimethylsilyl ethers under thermal conditions and microwave and ultrasonic irradiations.

  12-Tungstophosphoric acid immobilized on [bmim][FeCl4] was found to be an efficient catalyst for chemoselective methoxymethylation and ethxoymethylation of alcohols and also one-pot conversion of MOM- or EOM-ethers to their corresponding acetates and TMS-ethers under thermal conditions and microwave irradiation. These procedures were simple, rapid and the corresponding products were obtained in high yields. The catalyst exhibited remarkable reactivity and was reusable.

  Various types of hydroxy compounds can readily be converted to the corresponding mixed acetals with dialkoxymethanes in the presence of SAC-13 solid superacid. The transformation is almost instantaneous, product acetals are isolated in good to excellent yields, and the catalyst can be reused with minor loss of activity. Comparative studies were also carried out with p-toluenesulfonic acid and BF3 (.) OEt2.
