Aryllead-mediated synthesis of linear 3-arylpyranocoumarins: synthesis of robustin and robustic acid

The two naturally occurring linear 3-arylpyranocoumarins, robustin 1 and robustic acid 2, have been synthesised in nine steps from methyl 2,4,6-trihydroxyphenyl ketone, in 19percent overall yield for robustin and 18percent for robustic acid.Their synthese
