翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tert-Butyloxycarbonyl protecting group ： ウィキペディア英語版 Tert-Butyloxycarbonyl protecting group The ''tert''-butyloxycarbonyl protecting group (BOC group) is a protecting group used in organic synthesis. The BOC group can be added to the amine under aqueous conditions using di-''tert''-butyl dicarbonate in the presence of a base such as sodium bicarbonate. Protection of the amine can also be accomplished in acetonitrile solution using 4-dimethylaminopyridine (DMAP) as the base. Removal of the BOC in amino acids can be accomplished with strong acids such as trifluoroacetic acid neat or in dichloromethane, or with HCl in methanol. A complication may be the tendency of the ''t''-butyl cation intermediate to alkylate other nucleophiles; scavengers such as anisole or thioanisole may be used. Selective cleavage of the ''N''-Boc group in the presence of other protecting groups is possible when using AlCl3. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tert-Butyloxycarbonyl protecting group」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
