C-C键的形成反应是有机化学中最重要的基本反应.本文发展了一种简单、有效钯催化的α-溴代二硫缩烯酮与芳基硼酸的Suzuki-Miyaura偶联反应.该反应的实现,不仅建立了一种简单、有效合成α-芳基-α-烯酰基二硫缩烯酮化合物新方法,而且扩展了α-溴代二硫缩烯酮类化合物在有机合成中的进一步应用.
C-C bond formation is one of the most important reactions in organic synthesis.Here,a simple and efficient Pd(OAc)2-catalyzed Suzuki-Miyaura coupling reaction of α-bromo ketene dithioacetals with arylboronic acids has been developed.The reaction not only provides a simple,efficient,and new method for the synthesis of α-aryl-α-cinnamoyl ketene dithioacetals,but also further expands the synthetic potential of α-bromo ketene dithioacetals in organic synthesis.
