翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Reissert indole synthesis ： ウィキペディア英語版 Reissert indole synthesis The Reissert indole synthesis is a series of chemical reactions designed to synthesize indole or substituted-indoles (4 and 5) from ortho-nitrotoluene 1 and diethyl oxalate 2.〔Noland, W. E.; Baude, F. J. ''Organic Syntheses'', Coll. Vol. 5, p. 567 (1973); Vol. 43, p. 40 (1963). ((Article ))〕 Potassium ethoxide has been shown to give better results than sodium ethoxide. ==Reaction mechanism== The first step of the synthesis is the condensation of o-nitrotoluene 1 with a diethyl oxalate 2 to give ethyl o-nitrophenylpyruvate 3. The reductive cyclization of 3 with zinc in acetic acid gives indole-2-carboxylic acid 4. If desired, 4 can be decarboxylated with heat to give indole 5. 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「Reissert indole synthesis」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.
