摘要

The laccase-catalyzed oxidative coupling of sesamol, a naturally occurring phenolic antioxidant, with O₂ as the oxidant proceeds with high selectivity and delivers a previously unknown trimer in 61%yield. Further experiments demonstrate that the outcome of the sesamol oxidation strongly depends on the catalyst and the oxidant employed.
