A multicomponent domino reaction involving three mechanistically distinct Tf2NH-catalyzed reactions was developed. The reaction cascade enables the assembly of a skewed 5/6/4 tricyclic motif with migration of the reactive site with the assistance of a catalyst. The tricyclic product was used to achieve the first total synthesis of cytotoxic paesslerin A by regioselective C–H insertion of the sulfonyl

The present invention relates to the production of hydroxylated protoilludenes and/or sesquiterpenoid protoilludene-type aryl esters using newly identified genes that can be employed. The present invention accordingly relates to a host microorganism that has been transformed with the newly identified nucleotide sequences and to methods employing the transformed microorganism.
