A three-component reaction for 1,2-amino oxygenation of 1,3-dienes has been achieved using O-acyl hydroxylamines and carboxylic acids. The reaction occurs through copper-catalyzed amination of olefins followed by nucleophilic addition of carboxylic acids, offering high levels of chemo-, regio-, and site-selectivity. The method is effective for both terminal and internal 1,3-dienes, including those
使用O-酰基羟胺和羧酸已经实现了用于1,3-二烯的1,2-氨基氧合的三组分反应。该反应通过铜催化的烯烃的胺化,然后进行羧酸的亲核加成而发生,从而提供高水平的化学,区域和位点选择性。该方法对末端和内部1,3-二烯均有效,包括带有多个不对称取代基的那些。氨基氧合条件还显示出对烯烃的1,3-二烯显着的选择性,对敏感官能团的良好耐受性和可靠的可扩展性。
