In this present study, a series of 5-phenyl-2-furan and 4-phenyl-2-oxazole derivatives were designed and synthesized as phosphodiesterase type 4 (PDE4) inhibitors. In vitro results showed that the synthesized compounds exhibited considerable inhibitory ac

Both racemic 2-amino-3-(5-phenylfuran-2-yl)propionic acids and 5-phenylfuran-2-ylacrylic acids were synthesized and spectroscopically characterized (UV, EI-MS, 1H-NMR and 13C-NMR). The phenyl group of the 5-phenylfuranyl residue carried no (rac-la) para-Br (rac-lb) or Cl para or ortho (rac-lc, d) substituents. The novel furanylalanines were used as substrates of recombinant phenylalanine ammonia-lyase (PAL). When 50% of the racemic 5-phenylfuranylalanines were converted into the corresponding acrylates, the D-enantiomers of the substrates could be isolated. The L-enantiomers could be prepared from the substituted acrylates when the PAL reaction was reversed in the presence of 6 M ammonia at pH 10. The Japan Institute of Heterocyclic Chemistry.
Gold catalysis: Dihydroisobenzofurans and isochromanes by the intramolecular furan/alkyne reaction

A series of furyl alcohols and homofuryl alcohols was synthesized by reduction of furfurals or reaction of furyllithium compounds with epoxides and subsequent propargylation. The gold-catalyzed cycloisomerization of these products furnished dihydroisobenzofurans and isochromanes. Crystal structure analyses proved the sequence of the substituents for both classes of products. Unsaturated dicarbonyl compounds as side-products show the mechanistic relationship to the analogous platinum-catalyzed reactions. Neither ester groups, even on the 4-position of the furan ring, nor aryl bromides hinder the catalysis by gold. In the case of a substrate with an allyl ether in the side chain, a side-product, which provides evidence for a reaction of the alkyne with an inverse regioselectivity, was observed.
