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.

A series of 2-arylfuro[3,2-c]pyridines was synthesized. 3-(5-Aryl-2-furyl)propenoic acids 1a-1h were converted to the acid azides 2a-2h, which in turn were cyclized to give 2-arylfuro[3,2-c]pyridine-4(5H)-ones 4a-4h by heating in Dowtherm. The pyridones 4a-4f were aromatized with phosphorus oxychloride to the 2-aryl-4-chlorofuro[3,2-c]pyridines 5a-5f, which were reduced with zinc and acetic acid to the title compounds 6a-6f. Reacted with phosphorus(V) sulfide, the pyridones 4a-4f yielded the corresponding thiones 7a-7f.
