HClO4-silica-catalysed regioselective opening of benzylidene acetals and its application towards regioselective HO-4 glycosylation of benzylidene acetals in one-pot

- Regioselective reductive ring opening of 4,6-O-benzylidene acetals.
- Regioselective formation of 6-O-benzyl-gluco and mannopyranosides.
- Mild reaction condition, high yield and broad functional group compatibility.
- Tandem regioselective reductive ring opening and glycosylation in one-pot.
