Fungal Pigments, 49. - Synthesis of Grevillins and Related 2H-Pyran-2,5(6H)-diones

A convergent synthesis of grevillins 1 starts from diazoesters 6 which are converted into 3-aryl-2-oxopropyl ethyl oxalates 4 via bromoketones 7.Cyclization of 4 leads to pyrandiones 2 which are condensed with aromatic aldehydes to yield 4-aryl-2-benzylid
