O-heterocycles via laccase-catalyzed domino reactions with O2 as the oxidant

Laccase-catalyzed domino reactions of 4-hydroxy-6-methyl-2H-pyran-2-one or substituted 4-hydroxy-2H-chromen-2-ones with catechols using molecular oxygen as an oxidant afford coumestans and related O-heterocycles with yields ranging from 51% to 99%. Georg Thieme Verlag Stuttgart.
