Palladium(0)-catalyzed synthesis of 3,4-dihydro-2-methyl-ene-2H-1-benzopyran-4-ols via annulation between salicylaldehyde and propargyl carbonate using a formate reductant is reported herein. The annulation proceeds via common addition of the hydroxyl group in salicylaldehyde to the central carbon of η3-allenyl-/propargylpalladium, wherein the latter is generated through the oxidative addition of propargyl carbonate to the catalyst and subsequent intramolecular umpolung allylation of the aldehyde.
