Sulfuric acid magnesium salt (1:1) → HCID 18357908, compound

Participants

Reaction Steps

1.3 g (4 mmol) of 4-[3-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-1-propynyl]benzenemethanol and 20 ml of dichloromethane are introduced into a round-bottomed flask and 3.4 g (39.2 mmol) of manganese oxide are added. The mixture is stirred at room temperature for eight hours. Magnesium sulphate is added to the reaction medium, the mixture is filtered and the filtrate is evaporated. The residue obtained is purified by chromatography on a column of silica eluted with a mixture of ethyl acetate and heptane (10/90). After evaporation of the solvents, 930 mg (29.5%) of 4-[3-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-1-propynyl]benzaldehyde are collected in the form of a yellow oil.
