Procedure:
2,5-Dimercapto-1,3,4-thiadiazole (161.3 g, 1.08 mol) and alphapinene (161.3 g, 1.18 mol) were charged to a reaction vessel and cautiously heated to 120° C. (exothermic reaction). The reaction was maintained at 135° C. for one hour. The intermediate product was stripped under vacuum at 135° C. to remove any unreacted pinene and filtered hot. Methanol (200 ml), hexane (150 ml) and water (15 ml) were charged. The hexane layer was removed and discharded. The methanol layer was stripped of methanol by rotary evaporation and the intermediate product residue was mixed with toluene (200 ml) and then extracted with 1M sodium bicarbonate solution (50 ml). The toluene layer was dried over magnesium sulfate and the solvent removed by rotary evaporation. The yield was 134.1 g (0.468 mol) of the purified intermediate, 2-(2-pinanylthio)-5-mercapto-1,3,4-thiadiazole. This product was reacted with 1,2-epoxyhexadecane (112.3 g, 0.468 mol) by charging both reagents and isopropanol (100 ml) and bringing the reaction to reflux. The solvent was then stripped by rotary evaporation to afford the product.

Procedure:
To a solution of (1S,3R)-1,2,2-trimethylcyclopentane-1,3-dicarboxylic acid (5.1 g, 25.5 mmol) in methanol (63.7 ml) at −78° C. was added thionyl chloride (2.045 ml, 28.0 mmol). After stirring at −78° C. for 30 minutes, the reaction was allowed to warm to room temperature. Stirring was continued for 14 hrs. The reaction mixture was concentrated under reduced pressure, yielding a yellow oil. The oil was taken into water. The solution was adjusted to pH 12 with 1.0 N NaOH and was washed with ethyl acetate. The basic aqueous layer was acidified with 1.0 N HCl, and was extracted with ethyl acetate (3×, 100 ml). The ethyl acetate extracts were combined, dried with sodium sulfate, filtered, and concentrated under reduced pressure to afford (1S,3R)-3-(methoxycarbonyl)-1,2,2-trimethylcyclopentanecarboxylic acid (5.35 g, 24.97 mmol, 98% yield) as a colorless oil.
