Synthesis of 3-arylmuconolactones using biphenyl metabolism in Aspergillus
Mobley,Finkbeiner,Lockwood,Spivack
, p. 3273 - 3280 (1993)
Strains of the fungus Aspergillus form 3-arylmuconolactones as secondary products of the metabolism of biphenyl and substituted biphenyls. The 3-arylmuconolactones are not found to support growth and can accumulate to significant concentrations. The metabolic pathway leading from hydroxylated biphenyls to lactones appears to proceed through 3,4-catechol intermediates.

Paragraph 0018; 0020; 0022, (2016/11/14)
PROBLEM TO BE SOLVED: To provide novel dicyanate ester compounds which are excellent in heat resistance, humidity resistance and flame resistance, compared with known dicyanate ester compounds, have a low melting point and excellent solubility, compared with the p-terphenyl skeleton and exert excellent heat resistance, humidity resistance and substrate adhesion when used as a raw material for a curable resin. SOLUTION: Dicyanate ester compounds are of formula (1) and has a m-terphenyl skeleton. In formula (1), R1, R2 and R3 are independently an alkyl group, an alkoxy group, a phenyl group or a halogen atom; l, m and n are independently 0 or an integer of 1-4; for l equal to or greater than 2, R1's may be identical or different; for m equal to or greater than 2, R2's may be identical or different; and for n equal to or greater than 2, R3's may be identical or different.
