Yield: 83%
Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in hexane at 20;Inert atmosphere;
Steps:
1.6
(6) Take the compound (7R, 8S)-7,8epoxy-2-methyloctadecane-4-yne (F) (57mg, 0.2mmol) under the condition of 0-5 and hydrogen atmosphere Hexane (2mL) solution, and adding a palladium-carbon catalyst (6mg, 10wt%) to react at 20°C. After the reaction is completed, the catalyst is removed by filtration, the filter cake is washed with ethyl acetate, the filtrate is concentrated under reduced pressure, and purified by silica gel column chromatography to obtain a colorless liquid, which is the desired gypsy moth sex pheromone (+)-(7R, 8S) -7,8epoxy-2-methyloctadecane (I) (48 mg, 83%). After testing, the compound structure is correct.
