1-(2',4'-dihydroxy-3',5'-dimethylphenyl)-3-(2"-hydroxy-4",5"-methylenedioxyphenyl)-Propane, isolated from Iryanthera coriacea and I. laevis, 1-(2'-hydroxy-4'-methoxy-5'-methylphenyl)-3-(2"-hydroxy-4",5"-methylene-dioxyphenyl)-propane, isolated from I. laevis, and 1-(2'-hydroxy-4'-methoxyphenyl)-3-(3"-hydroxy-4"-methoxyphenyl)-propane, isolated from Virola multinervia, were synthesized by processes which involved catalityc hydrogenation of the appropriate chalcones and Clemmensen reduction of dihydrochalcones.Only the structures of 1,3-diarylpropanes isolated from V. multinervia and I. laevis were revised. - Keywords: Virola multinervia; Iryanthera coriaceae; I. laevis; Myristicaceae; 1,3-diarylpropanes; synthesis; reduction of chalcones and dihydrochalcones.
