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.
