Boron Halide Catalysed Regioselective ortho-Claisen Rearrangements of 4'-Allyloxycoumaric Acid Derivatives: Total Synthesis of Demethylsuberosin

6-Allyl-7-hydroxycoumarin 3 and the naturally occuring linear coumarin, demethylsunerosin (7-hydroxy-6-prenylcoumarin) 7 have been prepared in goods yields via regioselective boron halide catalysed ortho-Claisen rearrangements.This procedure provides an e
