We describe a 1,3-boron shift-type reaction of homoallenylboronates at the center (sp) carbon in allenes to afford 2-boryl-1,3-dienes with a variety of substituents. Notably, this reaction occurs with allenylboronates in the presence of carbamate and a small excess of -BuLi, and it is not necessary to isolate the unstable homoallenylboronates.
我们描述了一种在丙二烯中心（sp）碳上的高烯丙基硼酸酯的1,3-硼迁移型反应，以得到带有各种取代基的2-硼基-1,3-二烯。值得注意的是，该反应在氨基甲酸酯和少量过量的叔丁基锂存在下，与烯丙基硼酸酯发生，并且无需分离不稳定的高烯丙基硼酸酯。
