翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tert-Butyldiphenylsilyl ： ウィキペディア英語版 Tert-Butyldiphenylsilyl ''tert''-Butyldiphenylsilyl, also known as TBDPS or TPS, is a protecting group for alcohols. Its formula is C16H19Si-.〔http://www.organic-chemistry.org/protectivegroups/hydroxyl/tbdps-ethers.htm〕 ==Development== The ''tert''-butyldiphenylsilyl group was first suggested as a protecting group by Hanessian and Lavalle in 1975. It was designed to supersede the use of Corey's ''tert''-butyldimethylsilyl as a protecting group for alcohols: The novel features that they highlight are the increased resistance to acidic hydrolysis and increased selectivity towards protection of primary hydroxyl groups. The group is unaffected by treatment with 80% acetic acid, which catalyses the deprotection of O-tetrapyranyl, O-trityl and O-tert-butyldimethylsilyl ethers. It is also unaffected by 50% trifluoroacetic acid (TFA), and survives the harsh acidic conditions used to install and remove isopropylidene or benzylidene acetals.〔Hanessian, S; Lavelle, P; Can. J.
