官能团的保护和脱保护是诸多多步有机化学反应必须涉及的.文章报道了在温和条件下,磺酸功能化的介孔材料(SBA-15—SO3H)以及硅胶负载硫酸(SSA)均是有效的叔丁基二甲基硅基醚保护基团的脱保护催化剂.SBA-15—SO3H的循环使用效果优于SSA,而SSA的催化活性高于SBA-15—SO3H.
The protection and deprotection of functional groups must be involved in many multi-step organic chemical reactions. The report reports that sulphonic functionalized mesoporous materials (SBA-15-SO3H) and silica-loaded sulfuric acid (SSA) are all effective under mild conditions Of tert-butyldimethylsilyl ether protection group.SBA-15-SO3H recycling effect is superior to SSA, and the catalytic activity of SSA higher than SBA-15-SO3H.
