A suspension of 1.8 g of Raney-Ni (W-1) in 5 ml of ethanol was added thereto, and hydrogenation was carried out under hydrogen for about 5 hours so that 2405 ml of hydrogen (theoretical volume at 24° C.; 2465 ml) was absorbed. After filtering off the catalyst through a filter paper, the ethanol was evaporated. Yield 29.9 g. Silica gel column chromatography with benzene-hexane (1:1) gave 24.7 g of the title compound (yield 82.3%).

Afteradding a catalytic amount of 4-dimethylaminopyridine(DMAP), the reaction mixture was stirred at 30-35 °C for14 h. After completion of the reaction, crushed ice wasadded, and the reaction mixture was extracted withchloroform (3 × 25 mL). The combined chloroform extractwas washed with 6% aqueous HCl solution to remove thepyridine. Finally, the combined CHCl3 extract was washedwith distilled water and dried over anhydrous Na2SO4, andthe solvent was removed under vacuum. The resulting crudeproducts were separately purified by column chromatography(silica gel, 60-120 mesh, 24 g, column diameter2 × 30 cm) to afford the respective derivatives, 1-10, in highpurity (>95%).

After the reaction mixture was allowed to stand for 7 minutes, a solution (5.60 ml; 9.86 mmol) of t-butylperoxide (1.76 mol) in dichloromethane was added, and the whole was stirred at the same temperature for 105 minutes. Then, a solution of 2.01 g (6.77 mmol) of phytol, i.e., (3S,7R,11R)-1-hydroxy-3,7,11,15-tetramethyl-2-hexadecene (26) in 40 ml of dichloromethane, was added dropwise over 10 minutes, and the whole was stirred for 16 hours under the same conditions. Then, 6.0 ml of an aqueous 3N-K2 CO3 solution was added, and the reaction mixture was heated to a room temperature. Further, 4.0 g of celite was added 1 hour later, and the whole was stirred for 15 minutes. Then, the celite was filtered off, the filtrate was concentrated under a reduced pressure, diethyl ether and H2 O were added, and the organic layer was taken. The aqueous layer was extracted with diethyl ether. The resulting extract and the above organic layer were combined together, washed with an aqueous sodium chloride solution, and dried over magnesium sulfate. Thereafter, the solvent was evaporated under a reduced pressure to obtain 3.52 g of a crude product as a light yellow oil. The crude product was treated by column chromatography wherein 80 g of silica gel was used, and 2.00 g (yield: 95%) of the above-mentioned epoxide compound (201) was obtained as a colorless oil from the diethyl ether/n-hexane (1:4, v/v) effluent.

In water XXIV Preparation of 6,10-Dimethyl-2-undecanone: EXAMPLE XXIV Preparation of 6,10-Dimethyl-2-undecanone: Hydrogenation of Carbon-Carbon Double Bonds in the Presence of a Ketone Catalytic hydrogenation of 6,10-dimethyl-3,5,9-undecatrien-2-one, also known as pseudoionone (17.8 g, 92.6 mmoles, purchased from Pfaltz & Bauer, Waterbury, Conn.) was effected over 5% palladium on activated carbon (1.01 g) at room temperature and 2-3 atmospheres (H2 pressure) using ethyl alcohol (50 mL) as a solvent. After 30 minutes, the catalyst was removed by filtration through a small pad of Hyflo Super-Cel filtering aid. After dilution of the filtrate with 500 mL of water, the product was isolated by extraction (3*75 mL) with hexane. The combined extracts were dried over anhydrous magnesium sulfate and filtered. Removal of the volatile organic solvents by evaporation at reduced pressure, followed by distillation, afforded 15.95 g (87% yield) of the named ketone: boiling point 68°-72° C. at 0.15 mm. The identity of this known ketone was ascertained by proton NMR analysis. For use of this ketone to prepare phytol see: F. G. Fischer and K. Lowenberg, Ann., 475, 183 (1929).

After stirring for 10 min., 12 g (40 mM) of natural phytol in 30 ml of dry dichloromethane was added and then a dichloroethane solution containing 80 mM of t-butyl hydroperoxide was added. The reaction was monitored by thin layer chromatography (tlc). (CHCl3 -benzene solvent). After stirring for 2 hours at -20° C. to -30° C., 100 ml of 10% tartric acid solution was added and the drying bath was then removed. The organic layer was separated and washed with water. The dried organic solution was concentrated under water aspirator pressure to give 12.4 g of a colorless oil. This crude product was dissolved in 300 ml of diethyl ether and 120 ml of 1 N sodium hydroxide solution was added with ice cooling. After stirring for 30 min., the organic layer was separated, washed with water and dried over magnesium sulfate. This diethyl ether solution was concentrated under water aspirator pressure to give 12.2 g of a colorless liquid. This crude material was chromatographed on 200 g of 60 to 80 mesh silica gel.

With pyridine; dmap at 30 - 35℃; for 14h; General procedure for synthesizing phytol (PhY)derivatives 1-10 General procedure: Phytol (592 mg, 2 mmol) was dissolved in dry pyridine, andthe respective acyl/aryl chloride (3 mmol) was added. Afteradding a catalytic amount of 4-dimethylaminopyridine(DMAP), the reaction mixture was stirred at 30-35 °C for14 h. After completion of the reaction, crushed ice wasadded, and the reaction mixture was extracted withchloroform (3 × 25 mL). The combined chloroform extractwas washed with 6% aqueous HCl solution to remove thepyridine. Finally, the combined CHCl3 extract was washedwith distilled water and dried over anhydrous Na2SO4, andthe solvent was removed under vacuum. The resulting crudeproducts were separately purified by column chromatography(silica gel, 60-120 mesh, 24 g, column diameter2 × 30 cm) to afford the respective derivatives, 1-10, in highpurity (>95%).

With N-chloro-succinimide; dimethylsulfide In dichloromethane at 0 - 20℃; 57 Synthesis of mono-O-(3,7,11,15-tetramethylhexadec-2-enyl)erythritol Example 57 Synthesis of mono-O-(3,7,11,15-tetramethylhexadec-2-enyl)erythritol 0.90 g (6.7 mmol) of N-chlorosuccinimide was suspended in methylene chloride (8 mL). After addition of 0.52 mL (7.1 mmol) of dimethylsulfide at 0° C., the solution was stirred for 20 min. After addition of 1.0 g (3.4 mmol) of phytol, the mixture was stuffed for 1 hour at 0° C., and further stirred for 6 hours at room temperature. After addition of sodium bicarbonate aqueous solution, the reaction mixture was extracted with methylene chloride. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated to obtain 3,7,11,15-tetramethylhexadec-2-ene-1-chloride as a crude product.
