โœฆ Synopsis

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.
