Versuchsvorschrift
Following General Procedure G, ethyl 7-(7-ethoxy-4-isopropyl-2,2-dimethyl-2H-chromen-6-yl)-3-methyl-nona-2E,4E,6Z-trienoate (Compound 38,30 mg, 0.70 mmol) was hydrolyzed with 1M NaOH. Purification by column chromatography (silica gel, 30% ethyl acetate in hexanes) followed by recrystallization from acetonitrile gave rise to the title compound as a light yellow solid.
