PdII‐catalyzed decarboxylative Heck coupling of α‐alkoxyacrylates with (hetero)aryl carboxylic acids for the stereocontrolled production of (Z)‐β‐heteroarylated vinyl ethers is reported. This methodology offers a rational and step‐economical route to the family of attractive β‐arylated α‐alkoxy α,β‐unsaturated carboxylates, which is a relevant class of building blocks with different applications.
报道了Pd II催化的α-烷氧基丙烯酸酯与(杂)芳基羧酸的Heck偶联,用于立体控制(Z)-β-杂芳基化乙烯基醚的生产。这种方法为吸引人的β-芳基化α-烷氧基α,β-不饱和羧酸盐家族提供了一条合理,分步经济的途径,这是一类具有不同应用的重要组成部分。
