1-methoxy-5-(2-propenyl)-2-oxabicyclo[3.3.0]octane → HCID 57644359, compound

Participants

Reaction Steps

0.01 part of Lindler catalyst (manufactured by Aldrich Co.) was added to a solution of 0.2 part of a diastereomer (Isomer 5) of 1-methoxy-5-(2-propenyl)-2-oxabicyclo[3.3.0]octane obtained in Example 6 in 8 parts of methanol. The hydrogenation reaction was carried out at room temperature in a nitrogen atmosphere under a small hydrogen pressure for two hours. After the reaction, the catalyst was removed by filtration and the filtrate was concentrated under reduced pressure to obtain 0.2 part of one diastreomer (Isomer 7) of the target 1-methoxy-5-n-propyl-2-oxabicyclo[3.3.0]octane as a colorless oil (yield: 96%).
