YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In diethyl ether; water; (E,E)-α-Farnesene and (E)-β-ocimene. (E,E)-α-Farnesene and (E)-β-ocimene were synthesised from 3-methyl-2,5--dihydrothiophene-1,1-dioxide. See J. Chem Soc. Chem. Comm., 1984, 1323 (Chou et al.). Sulphur dioxide elimination was achieved using excess lithium aluminium hydride following a modified protocol based on that in Tetrahedron Lett., 1977, 11, 947 (Gaoni). To a stirred suspension of lithium aluminium hydride (1 equiv. by weight) in refluxing dry diethyl ether (10 mmol/ml) was added dropwise via syringe a solution of the dihydrothiophene-1,1-dioxide (1 equiv.) in dry diethyl ether (1 ml). After refluxing for 1 hour, the cooled (0 C.) mixture was treated with 15% NaOH (1 ml), water (3 ml), and the mixture filtered through Celite. Evaporation of the filtrate under reduced pressure followed by column chromatography over Florisil (100% hexane) yielded the product as a colourless oil. 4,8-Dimethyl-1,3,7-nonatriene.
