ethyl 2-(6-methoxy-3,4-dihydronaphthalen-1(2H)-ylidene)acetate → Ethyl 2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)acetate

Participants

Reaction Steps

To a solution of the alkene (512) (0.792 g, 3.22 mmol) in ethanol (53 mL) was added Pd/C (100 mg, 10% Degussa type). A balloon of hydrogen gas was added and the reaction was evacuated and back-filled with hydrogen three times. The reaction was stirred under a hydrogen balloon overnight at room temperature, then filtered through a pad of celite and concentrated in vacuo to give ethyl 2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)acetate (513) (0.708 g, 88.7%) as a colorless oil.
