Abstract: Three novel natural compounds, 3-farnesyl-2, 4, 6-trihydroxy-acetophenone (1),4-farnesyloxy-2, 6-dihydroxyacetophenone(2) and 6-farnesyl-3', 4', 5, 7-tetrahydroxy-flavanone (3) isolated from the aerial part of Boronia ramosa in Australia, were firstlysynthesized by starting from 2,4, 6-trihydroxyacetophenone and farnesyl bromide with total yield52.0%, 6.5% and 19.8%, respectively.The synthetic steps of compound 3 contained sixreactions of C-farnesylation, hydroxy-protection, aldol-condesation, cyclization andgroupdeprotection all together.

Key words: Farnesylacetophenone, Farnesylflavanone, 6-Farnesyl-3',4',5,7-tetrahydroxyflavanone, Total synthesis
