A new method for deprotecting tetrahydropyranyl and silyl ethers has been established by using organotin phosphate condensates as a catalyst. The reaction proceeds selectively under mild conditions. The heterogenous reaction enables easy separation of the catalyst, which can be reused for further reactions without purification.
利用
有机锡磷酸酯缩合物作为催化剂,已建立了一种脱除
四氢吡喃基和
硅醚保护基的新方法。该反应在温和条件下选择性地进行。由于反应为非均相,催化剂易于分离,无需进一步纯化即可重复用于后续反应。
