Participants

Reaction Steps

(E,E,E,E)-3,7-Dimethyl-9-(2,4,5-trimethyl-3-furyl)-2,4,6,8-nonatetraenoic acid ethyl ester (2.8 g.) was dissolved in ethanol (50 ml.) treated with potassium hydroxide (1.6 g.) in water (5 ml.) and heated at reflux for 30 minutes. After cooling to room temperature, water followed by acetic acid (until acid) was added and the solids were filtered off. Crystallization from ethylacetate gave pure (E,E,E,E)-3,7-dimethyl-9-(2,4,5-trimethyl-3-furyl)-2,4,6,8-nonatetraenoic acid (1.5 g.) m.p. 213°-214°.
