Two strategies for the functionalization of simple tetrahydroxanthones (THX) on either of the carbocyclicrings are reported. By application of palladium catalysis, concomitant assembly of this heterocyclic scaffold with controlled introduction of substituents on the aromatic ring at C-5, C-6 or C-7 can be achieved. Variation in the nature of the added carbon fragment (aryl, alkenyl and alkynyl) is

Mycotoxins of the tetrahydroxanthone class of natural products possess a large number of interesting biological properties. In this full paper, we present our synthetic strategy to some members of this class of compounds, namely the blennolides A and C. We disclose the scope and limitations of the functionalization of various xanthones derived from a domino oxa-Michael-aldol condensation and pursue
