A one‐step conversion of ketones into N‐acetyl enamides was developed. The process employs safe and inexpensive reagents, proceeds under mild conditions, and tolerates diverse functional groups. The addition of edte (N,N,N′,N′‐tetrakis(2‐hydroxyethyl)ethylenediamine) prior to workup enables water solubilization of Ti alkoxides and allows a simple extractive workup.
开发了将酮一步转化为N-乙酰基酰胺的方法。该方法使用安全且廉价的试剂,可在温和条件下进行,并能耐受各种官能团。在后处理前添加edte(N,N,N ',N'-四(2-羟乙基)乙二胺)可使Ti醇盐水溶性化并进行简单的萃取后处理。
