The synthesis of allenyl-Bdan has been realized via the Cu(I)-catalyzed borylation of propargylic alcohols. This methodology offers a facile and efficient pathway toward allenyboronates with diverse functional groups due to the simple access to the substrates. The substrates bearing ester groups are well-tolerated in the synthesis of allenyl-Bdan under the Lewis acidic conditions. The structures of two allenyl-Bdan were further confirmed via single-crystal X-ray diffraction.

通过不对称Diboron试剂（Bpin-Bdan）的Cu（I）催化炔丙基醇的硼化反应合成烯基-Bdan。

烯丙基-Bdan的合成已通过Cu（I）催化的炔丙醇的硼化反应实现。由于易于接近底物，该方法为具有不同官能团的烯丙基硼酸酯提供了一种简便而有效的途径。在路易斯酸性条件下合成烯基-Bdan时，带有酯基的底物具有良好的耐受性。通过单晶X射线衍射进一步证实了两个烯基-Bdan的结构。
