DIHYDROEUGENOL synthesis

13synthesis methods
By catalytic reduction of eugenol with a palladium- or platinum-black catalyst.
-

Yield:2785-87-7 98%

Reaction Conditions:

with hydrogen in methanol at 20; for 20 h;chemoselective reaction;

Steps:

4.3. Typical procedure for the chemoselective hydrogenation
General procedure: The mixture of the substrate (0.250 mmol), 0.5% Pd/MS3A or 0.5% Pd/MS5A (10 wt % of the substrate) and MeOH (1 mL) was stirred under H2 atmosphere (balloon) at room temperature. After a given period, the reaction mixture was filtered through a membrane filter (Millipore, Millex-LH, 0.45 mm), and the filtrate was concentrated in vacuo to produce the corresponding reduced product.
