An efficient double addition of substituted alkenylmagnesium bromides to bis-Weinreb amides has been developed, giving α,ω-bis-enones that are building blocks for certain drugs and polymers. Furthermore, reliable protocols for the preparation of the requi

(Chemical Equation Presented) The tail makes the difference: Removing the isopropylidene acetal unit from well-known TADDOL ligands improved the performance of the derived phosphoramidite ligands in asymmetric gold catalysis (see scheme; Ts=4-toluenesulfonyl). X-ray crystallography showed that the binding pocket has an effective three-fold symmetry, with through-space interactions between the arene rings of the ligand and the gold center.
