Ethyl acetimidate
WebJan 25, 2024 · An efficient synthesis of ethyl acetohydroximate (EAH) and derivatives was developed. EAH was synthesized from ethyl acetimidate hydrochloride, which was prepared from acetonitrile and ethanol in the presence of acetyl chloride, with hydroxylamine and potassium carbonate. WebFeb 17, 2024 · When ethyl acetimidate was used instead of 2a, we found that the yield was only 20 % under optimal conditions, and the yield was raised to 52 % when the reaction time was extended to 24 h ( Table 1, entry 11). This result demonstrated that the electron-withdrawing property of the trichloro ethyl group was essential for the transformation.
