- Photoinduced Palladium-Catalyzed Negishi Cross-Couplings Enabled by the Visible-Light Absorption of Palladium–Zinc Complexes
-
A visible-light-induced Negishi cross-coupling is enabled by the activation of a Pd0–Zn complex. With this photocatalytic method, the scope of deactivated aryl halides that can be employed in the Negishi coupling was significantly expanded. NMR experiments conducted in the presence and absence of light confirmed that the formation of the palladium–zinc complex is key for accelerating the oxidative addition step.

- Dioxolanones as Synthetic Intermediates. Part 3. Biomimetic Synthesis of Pulvinic Acids
-
The reaction of the phosphorane (16) with methyl arylglyoxylates gives 5-(α-methoxycarbonylarylidene)-2,2-pentamethylene-1,3-dioxolan-4-ones which have been treated with the lithium enolates of t-butyl phenylacetic esters to provide a biomimetic synthesis of pulvinic acids.By this method pulvinic acid (2), vulpinic acid (1), and the unsymmetrically substituted compounds, leprapinic acid (3), and xerocomic acid (4) have been prepared; the last named was obtained via an intermediate (28) in which the phenolic groups were protected as benzyl ethers.
