✦ Synopsis
The role of 4-dimethylallyltryptophan as the first intermediate in the pathway of clavine alkaloid biosynthesis appears to be well established (1,2). Hydroxylation of one of the methyl groups of 4-dimethylallyltryptophan has been proposed as the next step in the biosynthetic path-

Torosachrysone (2) is correlated over six steps without the need for intermediate purification with methyl R-(+)-tetrahydro-2-methyl-5-oxo-2-furanacetate ( 16); the method is applicable in principle to a large number of more complex dihydroanthracenones of as yet indeterminate stereochemistry.
