Abstract: The invention relates to a method for producing compounds of formula whereby: a) a bicyclic olefin of formula is reacted with haloform in the presence of a base to produce the ring-enlarged product of formula b) the compound of formula (III) is hydrolyzed to produce the allyl alcohol of formula c) the allyl alcohol of formula (IV) is oxidized to produce the unsaturated ketone of formula (V); d) the ketone of formula (V) is reacted with a nucleophilic ion Y, which stabilizes a negative change, to produce the ketone of formula and; e) the ketone of formula (VI) is hydrolyzed to produce the bicyclic 1.3-diketone of formula (I). In formulas (I) to (VI), R1-R5, X, Y and Z have the meanings as cited in the description. The invention also relates to novel intermediate products and to novel methods for producing these intermediate products. 19 claims
