Studies on the total synthesis of mumbaistatin, the -strongest natural inhibitor of G6P-T1, have culminated in the synthesis of a 4′′,8-dideoxy analogue. Keysteps include a Diels-Alder reaction for the construction of the functionalized anthraquinone, a palladium-catalyzed Stille coupling to generate a tetra- ORTHO-sub-stituted diarylmethane, and a titanium-mediated alkynylation of an aldehyde to

The present invention relates to a process for preparing mumbaistatin derivatives (I), where the anthraquinone skeleton is constructed via a Diels-Alder reaction and the central methylene bridge via a transition metal-catalyzed reaction, and to the intermediates used in this process.
