Trityl ethers are selectively deprotected to the corresponding alcohols in high yields by CBr4 in refluxing methanol under neutral reaction conditions. Other hydroxyl protecting groups like isopropylidene, allyl, benzyl, acetyl, benzoyl, methyl, tosyl, prenyl, propargyl, tert-butyldiphenylsilyl and p-methoxybenzyl ethers are unaffected.
在中性反应条件下,在回流的甲醇中,通过CBr4将三苯甲基醚高选择性地脱保护为相应的醇。其他羟基保护基如异亚丙基,烯丙基,苄基,乙酰基,苯甲酰基,甲基,甲苯磺酰基,异戊二烯基,炔丙基,叔丁基二苯基甲硅烷基和对甲氧基苄基醚不受影响。
