The directed methallylation of β-hydroxyaldehydes and ketones with methallyboronic acid is examined. The reaction proceeds with good to excellent selectivity with ketones.

A strategy for the synthesis of spirocarbocycles by using chloromethyl arenes as starting materials is described in this paper. The palladium-catalyzed allylative dearomatization and the subsequent ruthenium-catalyzed ringclosure metathesis proceeded smoothly under mild conditions to produce the corresponding spirocarbocycle products with moderate to high yields. Benzene-ring-, naphthalene-ring-,
