  Target-oriented synthesis: miscellaneous synthetic routes to access 1,4-enediones through the coupling of 1,3-dicarbonyl compounds with multiform substrates

  摘要：

  Target-oriented synthetic protocol was presented for the synthesis of 1,4-enediones. The approach can efficiently construct 1,4-enediones through different reaction pathways from multiform substrates alpha-halo aromatic ketones, 2-hydroxy-aromatic ketones and methyl carbinols. In this reaction, CuI was found to be the most efficient catalyst. Multiform substrates were also found to perform well to afford the products in a one-pot fashion. (C) 2013 Elsevier Ltd.

  A highly efficient synthesis of unsymmetrical 1,4-enediones from 1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes has been developed via a focusing domino strategy. Simple and readily available starting materials, mild reaction conditions, and a very simple operation are advantages of the reaction, which allow straightforward synthesis of a variety of unsymmetrical 1,4-enediones

  通过聚焦多米诺骨牌战略已开发出一种由1,3-二羰基化合物和甲基酮或末端芳基烯烃高效合成不对称1,4-二烯键的方法。简单且容易获得的起始原料，温和的反应条件和非常简单的操作是反应的优势，可以直接合成各种不对称的1,4-二烯酮。
