Total syntheses of zaragozic acids A and C by a carbonyl ylide cycloaddition strategy

A carbonyl ylide cycloaddition approach to the squalene synthase inhibitors zaragozic acids A and C is described. The carbonyl ylide precursor 8 was synthesized starting from di-tert-butyl D-tartrate (47) via an eleven-step sequence involving the regiosel

Total Synthesis of the Squalene Synthase Inhibitor Zaragozic Acid C by a Carbonyl Ylide Cycloaddition Strategy

Ketal isomers avoided. The unique 2,8-dioxabicyclo[3.2.1 ]octane core of zaragozic acid C (1) was constructed in a Rh-catalyzed 1,3-dipolar cycloaddition of an alkyne to an ester carbonyl ylide. Another feature of this improved synthesis is the constructi
