The protocol is general, mild and efficient. It was suitable for various terminal sugar alkynes and aroyl chlorides, with 37 selected examples. The sugar substrates include pyranosides, furanosides, and acyclic sugars with sensitive and bulky protecting groups. The aroyl chlorides contain electron-donating, electron-withdrawing and electron-neutral substituents. 收起
