Application of dibutyltin oxide method to regioselective acylation and alkylation of tylosin at C-4''.

K Kiyoshima et al.

Chemical & pharmaceutical bulletin, 37(4), 861-865 (1989-04-01)

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

Mild and selective deprotection method of acetylated steroids and diterpenes by dibutyltin oxide.

Shao-Min Wang et al.

Steroids, 72(1), 26-30 (2006-12-30)

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
