Progress in the synthesis of the lituarines: Stereocontrol in sequential C-C bond formation on a spirobutenolide template

(Chemical Equation Presented) We describe elaboration of a tricyclic spirobutenolide corresponding to the C(7-18) tricyclic substructure common to lituarines A-C. Conjugate addition, to install the C(16) methyl, is followed by construction of the crucial
