A cyclodehydrating agent is needed to catalyze the reaction It is named after Sir Robert Robinson and Siegmund Gabriel who described the reaction in 1909 and 1910, respectively. 2-Acylamino-ketones can be synthesized using the Dakin–West reaction. ==Reaction mechanism== The first part of this reaction is the cyclization of an 2-acylamidoketone that contains all three oxazole substituents. The second part is a dehydration, removing water from the molecule. Labeling studies have determined that the amide oxygen is the most Lewis basic and therefore is the one included in the oxazole. 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「Robinson–Gabriel 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.
