Reaction Steps

196.5 g of ethyl (E)-3-(3-methoxy-4-methoxymethoxy-5-propyl-1-naphthyl)-2-methylpropenoate was dissolved in 2.6 liters of acetone and irradiated with light from a high pressure mercury lamp through a Pyrex filter for 2.5 hours. The reaction mixture was concentrated in vacuo and purified by silica gel column chromatography (3% ethyl acetate/hexane) to obtain 59.2 g of the titled compound as a pale yellow oil. At the same time, 136.4 g of a mixture of the E and Z isomers was recovered.
