biologically interesting geranylated flavanones and geranylated chalcones is described. Thus, the first total syntheses of the geranylated flavanones (±)‐prostratol F (1), (±)‐8‐geranyl‐3′,4′,7‐trihydroxyflavanone (2), and (±)‐6‐geranyl‐5,7‐dihydroxy‐3′,4′‐dimethoxyflavanone (3) were carried out starting from 2,4‐dihydroxyacetophenone (10) and 2,4,6‐trihydroxyacethophenone (17) in five to six steps (Schemes 2
