Benzophenones are derived from several pathways. In higher plants, most benzophenones arise by cyclization of a polyke-tide chain of three malonates added to a hydroxybenzoic acid precursor (Manitto, 1981). Cyclization occurs via a Claisen condensation mechanism (Fig. 10.14). These compounds serve as precursors for xanthones in many plants. In some instances [e.g., in the heartwood of Symphonia globulifera (Clusiaceae)], the benzophenone and the corresponding xan-thone co-occur [in this case maclurin (33) and 1,3,5,6-tetra-hydroxyxanthone (34)] (Weiss and Edwards, 1980). 

Maclurin (33) and two related cyclization products that are found in the heartwood of Symphonia globulifera (Clusi-aceae) possibly arise by ring closure of a benzophenone precursor (Weiss and Edwards, 1980).
