実験手順
14 g of the hydroxyketoaldehyde of formula XIII obtained in Example 26 are dissolved in 200 ml of diethyl ether. 20 ml of pyridine are added to the solution at 0° C. and 12 g of phenoxyacetic acid chloride are then added dropwise. The mixture is stirred for 2 hours at 0° C. and then poured into water and extracted with diethyl ether. The 5-[2,6,6-trimethyl-3-oxo-4(S)-(phenoxyacetoxy)-cyclohex-1-en-1-yl]-3-methyl-penta-2,4-dien-1-al (IIA) is isolated from the ether extract.
