An efficient synthesis of α-amino ketones is developed using the umpolung strategy. Umpoled enolates such as N-alkenoxypyridinium salts react smoothly with diverse amines to give α-amino ketones via an SN2′ pathway. This umpolung strategy overcomes the drawbacks of traditional methods such as the need for prefunctionalized ketone derivatives. Our method also offers good chemical yields and high functional
使用umpolung策略开发了α-氨基酮的有效合成方法。诸如N-烯氧基吡啶鎓盐之类的酚醛树脂与各种胺能顺利反应,通过S N 2'途径生成α-氨基酮。这种抗药性策略克服了传统方法的缺点,例如需要预官能化的酮衍生物。我们的方法还具有良好的化学收率和较高的官能团耐受性。
