実験手順
The starting material phenylpropane derivatives such as dihydroeugenol (n-Propyl guaiacol), 3,4-Methylenedioxy phenylpropane (dihydrosafrole), 4-Methoxyphenylpropane (dihydroanethole) or the like, can be obtained either from commercial sources or by catalytic hydrogenation of corresponding eugenol, safrole, anethole derivatives respectively (Steffen, A. In: Perfume and Flavor Chemicals, Allured Punlishing Corporation, 362 South Schmale Road, Carol Stream, Ill., USA, (1994)). In addition, 2,4,5-Trimethoxyphenylpropane can be obtained via ammonium formate assisted reduction of toxic β-asarone of Acorus calamus or crude calamus oil containing β-asarone (Sinha, A. K., U.S. Ser. No. 09/652,376 filed on Aug. 31, (2000)).
