Syntheses of Two Microbial Metabolites, 5-Chloro-3,4-dihydro-8-hydroxy-6-methoxy-3-methylisocoumarin and 8-hydroxy-6-methoxy-3-methylisocoumarin

The racemate of 5-chloro-3,4-dihydro-8-hydroxy-6-methoxy-3-methylisocoumarin (I), a fungal metabolite of Periconia macrospinosa, was synthesized from 6-chloro-3,5-dimethoxyhomophthalic acid (III) via compounds IV, VI, VII and VIII.Catalytic hydrogenation
