Studies on the reactivity of a tertiary allylic alcohol in an acetophenonic series, a model for natural products synthesis

The synthesis of benzopyranic simplified analogues of dibenzopyranic natural compounds is described, together with the access to a precursor of a new furobenzopyranic natural product. These natural products have anti‐cancer activity. The 1,3‐diacetoxy‐2‐acetyl‐4‐(3‐hydroxy‐3‐methylbut‐1‐enyl)benzene synthone is used as a common precursor to these structures.
