  Microwave-promoted, one-pot conversion of alkoxymethylated protected alcohols into their corresponding nitriles, bromides, and iodides using [bmim][InCl4] as a green catalyst

  摘要：

  The Lewis acid room temperature ionic liquid, [bmim][InCl4], was found to be an efficient and green catalyst for the highly chemoselective and one-pot conversion of MOM- or EOM-ethers into their corresponding nitriles, bromides, and iodides under microwave irradiation. The procedures are simple, rapid, and high yielding. The catalyst exhibited a remarkable reactivity and is reusable. (C) 2010 Elsevier Ltd. All rights reserved.

  methoxymethyl (MOM) and ethoxymethyl (EOM) ethers in the presence of catalytic amounts of H3PW12O40 at room temperature under solvent-free conditions. Selective protection of primary and secondary alcohols in the presence of phenols and tertiary alcohols was achieved by this method. Deprotection of these ethers to their parent alcohols was also performed using this catalyst in ethanol under reflux conditions

  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、

  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.
