Total synthesis of fulvic acid (1a) is described.Regioselective cyclization of the enedione (8f), an equivalent of the proposed biogenetic intermediate (5a) for citromycetin (2), gave the pyrone (11a), which led to fulvic acid (1a) by a route involving debenzylation, selective ozonization, and hydration.

Synthesis of fulvic acid (1a) was accomplished by a route involving selective ozonization of 9-propenylpyranobenzopyran (1c), obtained by a regioselective cyclization of the 2-methylsulphinylmethyl 1,3-dione (3c).
