实验步骤: Farnesol (3.00 g, 13.5 mmol) was dissolved in methanol (30 ml), Pt/C (2%, 0.30 g) was suspended therein and the suspension was stirred overnight under a hydrogen atmosphere. After completion of the reaction, Pt/C was removed by filtration, and the filtrate was concentrated to give 3,7,11-trimethyldodecan-1-ol. This was used for the next reaction without purification. was removed by filtration the filtrate was concentrated

实验步骤: Farnesol (572 g, 2.58 mole, 650 mL) was added to a 1000 mL Parr high pressure vessel containing 10% Pd/C (23 g, 4% by weight of farnesol). The reaction vessel was sealed and evacuated under house vacuum for 5 minutes after which time the reaction mixture was pressurized with H2 to 1000 psi. The reaction mixture was stirred at 25° C. and judged to be complete by thin layer chromatography (“TLC”, Rf=0.32, 90:10 hexane:ethyl acetate) after approximately 12 hours. The reaction vessel was depressurized under vacuum followed by venting to a N2 atmosphere. The reaction contents were vacuum filtered over a silica gel (60 Å from Aldrich) pad followed by washing of the silica gel with ethyl acetate (“EtOAc”, 3 L). The filtrate was concentrated on a rotary evaporator. The isolated product was further dried under high vacuum to remove any residual EtOAc to afford 3,7,11-trimethyldodecan-1-ol as a lightly tinted yellow viscous liquid. 1H-NMR (CDCl3, 500 MHz): δ 3.71 (m, 2H), 1.65-1.05 (m, 17H), 0.89-0.83 (overlapping t&d, 12H).

实验步骤: Farnesol (200 g) was dissolved in ethanol (1000 ml), added with platinum oxide (1 g) and stirred for 24 hours at room temperature under hydrogen atmosphere. After the completion of the reaction, insoluble material was removed by filtration through a Celite layer and the filtrate was concentrated under reduced pressure to obtain 3,7,11-trimethyldodecanol (195 g). After the completion of the reaction, insoluble material was removed by filtration through a Celite layer the filtrate was concentrated under reduced pressure
