Abstract Amberlyst-15 catalyzed highly regioselective tritylation of sugar-based diols was achieved under mild condition using 4,4′-dimethoxytrityl alcohol (DMTrOH). Deprotection of the corresponding DMTr group was also established by the variation to protic solvent. Meanwhile, the heterogeneous catalyst Amberlyst-15 was recycled 3 times with satisfactory retention of catalytic activity and proved
摘要在4,4'-二甲氧基三苯甲基醇(DMTrOH)的温和条件下,Amberlyst-15催化了糖基二醇的高区域选择性三苯甲基化反应。通过向质子溶剂的变化也建立了相应的DMTr基团的脱保护。同时,均相催化剂Amberlyst-15循环使用了3次,保持了令人满意的催化活性,证明了其在工业中的潜在应用。
