Application
Dibutyltin(IV) oxide (Bu2SnO) can be used as a reagent to prepare:
- Substituted oxazoles via reaction of dibutyltin diacylates with 1-substituted acetylenes and trimethylsilyl azide.
- Triazolyl-substituted benzyloxyacetohydroxamic acids as potential LpxC inhibitors.

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

Regioselective formation of 6-O-acylsucroses and 6,3'-di-O-acylsucroses in one pot with good yields was achieved for the first time by a typical acylation method of sucrose via its dibutylstannylene acetal. Pure monoesters at OH-6 and diesters at OH-6,3' obtained by these

Dibutyltin oxide (DBTO) was first utilized for the deacetylation of steroid and diterpene esters. The results showed the deprotection of acetylated steroids and diterpenes separately with moderate catalysis dibutyltin oxide in methanol selectively removed part acetyl groups of these substrates

Dibutyltin oxide-mediated regioselective chloroacetylation of methyl 1-thio-beta-xylobioside, followed by treatment of the product with 4-methylbenzoyl chloride-pyridine, gave methyl 4-O-chloroacetyl-2,3-di-O-(4-methylbenzoyl)-beta-D-xylopyranosyl-(1-->4) -2.3-di - O-(4-methylbenzoyl)-1-thio-beta-D-xylopyranoside (18) in 70% yield. Coupling of 18 with benzyl alcohol afforded the disaccharide benzyl beta-glycoside, which was O-dechloroacetylated
