Enones acyclic trisubstituted

A wide range of acyclic trisubstituted enones readily undergo ECA with both commercially available trialkylaluminium reagents and the in situ-generated aryl (dialkyl)aluminium reagents. Very low catalyst loadings are sufficient (0.5-3.0 mol %) and products are formed in good yields (33-95%) and exceptional enantio-selectivities (80 to 99%) (Scheme 28) [65]. [Pg.61]

Related chiral phosphine peptide ligands have been successfully utilized for ACA to acyclic aryl and aliphatic enones (eq 104), trisubstituted cyclic enones (eq 105), cyclic nitroaUcenes (from which a-substituted ketones can be prepared via a Nef reaction) (eq 106), and unsaturated A-acyloxazolidinones (eq 107).
