General description

Dibutyltin(IV) oxide is an organotin compound that is commonly used as a Lewis acid catalyst in organic synthesis. For instance, it can be used for the formation of carbon-carbon bonds through coupling reactions and in the preparation of esters from carboxylic acids and alcohols. It also finds use in allylation reactions, cycloaddition reactions, and ring-opening polymerizations.

4''-O-Acyl-, 4''-O-alkyl- and 4''-deoxy-tylosin derivatives were synthesized using 2'-O-acetyl-3'',4''-O-(dibutyl-stannio)tylosin as a synthetic intermediate. The in vitro biological evaluation showed that the new derivatives were active against macrolide-resistant clinical isolates of bacteria and mycoplasmas, and that they were resistant to hepatic

The reaction process for the selective deprotection of acetylated glucosides by dibutyltin oxide in methanol is investigated by using methyl 2,3,4,6-tetra-O-acetyl-α-d-glucopyranoside as a model substrate with ESIMS and NMR techniques. According to the results, it is inferred that at first
