Regiocontrolled Construction of Furo[3,2‑<i>c</i>]pyran-4-one Derivatives by Palladium-Catalyzed Cyclization of Propargylic Carbonates with 4‑Hydroxy-2-pyrones
The reaction of propargylic carbonates with 4-hydroxy-2-pyrones
in the presence of a palladium catalyst is described. By the choice
of the reaction temperature, two types of the substituted furoÂ[3,2-<i>c</i>]Âpyran-4-one derivatives were regioselectively synthesized,
respectively

Palladium-Catalyzed C–H Monoalkoxylation of α,β-Unsaturated Carbonyl Compounds
An
efficient method for the direct introduction of alkoxy groups
into the β-position of alkene moieties of various α,β-unsaturated
carbonyl compounds through the palladium-catalyzed CÂ(sp<sup>2</sup>)–H monoalkoxylation using alcohols in the presence of sodium
nitrite was developed; the corresponding enol ethers were selectively
synthesized with minimal generation of acetals
