The synthesis is described of a bis-ene-1,2-dithiolate pro-ligand, designed to model the stereochemical situation in the cofactor of the tungsten enzyme ferredoxin aldehyde oxidoreductase from Pyrococcus furiosus. Each masked ene-1,2-dithiolate unit is mounted on a pyrano[2,3-b]tetrahydroquinoxaline tricycle, comparable to the pyrano[2,3-g]tetrahydropteridines found in all molybdoenzymes and tungsten
