Synthesis of Zaragozic Acid A/Squalestatin S1

A novel synthetic approach to the construction of the zaragozic acids, which was used for the asymmetric synthesis of zaragozic acid A/squalestatin S1 (1), is described.Fragment 5, representing the tricarboxylic acid core portion, is assembled in three ke
