Total synthesis of the macrodiolide pyrenophorol

By means of a total synthesis, the absolute configuration of the naturally occurring macrodiolide pyrenophorol has been established. An essential step is the photo-induced rearrangement of an α,β-epoxy diazomethyl ketone to produce a 4-hydroxy-2-alkenoate. The two lactone units have been introduced in two successive steps.
