A new two-step procedure was developed by carbozincation of internal and terminal alkynes to synthesise highly functionalised vinylzinc bromides. Various tri and tetrasubstituted alkenes were prepared in moderate to good yields under mild reaction conditions in a stereo-selective manner. This methodology represents an interesting alternative to previously known methods.
一种新的两步法被开发出来,通过对内烯和末端炔的碳锌化反应合成高功能化的乙烯基锌溴化物。在温和的反应条件下,以立体选择性的方式制备了多种三取代和四取代烯烃,产率中等到好。这种方法代表了一种有趣的替代方案,优于已知的其他方法。
