available ketone-derived cyanoamides with NaOtBu leads to enamides in a simple, scalable, and inexpensive one-step operation in good yield. Enamides not stabilized by conjugation or by inclusion in a ring can also be prepared. An E1cB mechanism consistent with all results and observations, is proposed. The Z geometry of the product enamide is highly favoured, and the regioselectivity can be directed
用 NaOtBu 处理容易获得的酮衍生的氰胺,可以通过简单、可扩展且廉价的一步操作以良好的收率获得烯酰胺。也可以制备未通过共轭或包含在环中而稳定的烯酰胺。提出了与所有结果和观察结果一致的 E1cB 机制。产物烯酰胺的 Z 几何结构受到高度青睐,区域选择性可以通过保护基团的选择来指导。
