摘要：

The two naturally occurring linear 3-arylpyranocoumarins, robustin 1 and robustic acid ?, have been synthesised in nine steps from methyl 2,4,6-trihydroxyphenyl ketone, in 19% overall yield for robustin and 18% for robustic acid. Their syntheses involved, as a key step, the regioselective arylation of a functionalised 4-hydroxybenzo [1,2-b:5,4-b']dipyran-2-one with the appropriate aryllead triacetate.
