A highly efficient Pd-catalyzed cyclizative borylation reaction of allenyl ketones has been developed. The transformation is based on carbene boryl migratory insertion using starting materials that are modularly assembled from raw building blocks. This borylation reaction is a reliable method to synthesize various borylated furans, from which previously hard-to-obtain tetra-substituted furans can be
