Highly efficient arylations of β‐chloro ketones and their ester and amide derivatives were achieved by means of domino dehydrochlorination/Rh(I)‐catalyzed conjugate addition. In situ generated vinyl ketones and their analogues were identified as the reaction intermediates. The present synthetic protocol provides a concise route to (chiral) β‐aryl ketones, esters, and amides.
β-氯酮及其酯和酰胺衍生物的高效芳基化是通过多米诺脱氢/ Rh(I)催化的共轭物加成反应实现的。原位生成的乙烯基酮及其类似物被鉴定为反应中间体。本合成方案为(手性)β-芳基酮,酯和酰胺提供了一条简明的途径。
