MUSHROOM TYROSINASE CATALYSED SYNTHESIS OF COUMENTANS, BENZOFURAN DERIVATIVES AND RELATED HETEROCYCLIC COMPOUNDS

Full details of an improved synthesis of coumestan derivatives and their structural analogues, viz., wedelolactone, 11-hydroxy aureol, 11-hydroxy coumestrol along benzofuran derivatives and related heterocyclic systems are reported by coupling of in situ generated o-quinones from catechols catalysed by mushroom tyrosinase with various reatants.
