Better late than never! Almost 200 years after Pelletier's pioneering studies on the chemical constituents of red sandalwood, the major santalins and santarubins have been synthesized. This efficient approach integrates a Knochel isoflavonoid synthesis with Friedel-Crafts allylations or olefin metatheses, and a final biomimetic reaction cascade that furnishes the venerable benzoxanthenone dyes in a single operation (see scheme).
