A new synthetic approach to the synthesis of some epimeric C-4-hydroxybenzo[c]pyrans is described. A key step in their formation is stereoisomerisation of a nonconjugated ortho alkenylphenylketone and -ester using palladium bisacetonitrile [bisacetonitril

A general synthetic strategy has been developed for the synthesis of racemic 3,4-dihydro-3-methyl-1H-benzopyran-5,8-dione 25, trans-(1R,3R)-5,8-dihydroxy-1,3-dimethyl-4-oxo-1H-benzopyran 39, rel (1R,3R,4R)-3,4-dihydro-1,3-dimethyl-4-hydroxy-1H-benzopyran-5,8-dione 41 and the rel-(4S)-diastereoisomer 42.
