The direct, photoacid‐catalyzed synthesis of 2‐deoxyglycosides from glycals is reported. A series of phenol‐conjugated acridinium‐based organic photoacids were rationally designed, synthesized, and studied alongside the commercially available phenolic catalyst eosin Y. In the presence of such a photoacid catalyst and light, synthetic glycals were activated and coupled with a range of alcohols to afford
据报道,由糖类直接,光酸催化合成了2-脱氧糖苷。与市售的酚催化剂曙红Y一起,合理设计,合成和研究了一系列基于酚共轭啶基的有机光酸。在这种光酸催化剂和光的存在下,合成糖被活化并与多种醇偶联以高收率和优异的α-选择性提供2-脱氧糖苷。
