Evans-Metternich

The same natural product was synthesized by Paterson et al. [45] who assembled the carbon skeleton of the macrolide from three larger subunits as well. Instead of the Evans-Metternich variant they used their boron-mediated antz-selective aldol strategy which relies as the Evans-Metternich aldol on stereo-induction from the a-chiral center and translates the E-enolate geometry, established due to the use of Cy2BCl, to the anti aldol product (Scheme 33). [Pg.74]
