摘要

Under these conditions with (S,S)-3b, several other α,β-unsaturated Weinreb amides bearing a primary alkyl, a secondary alkyl, or an aryl group at the β-position can also be phenylated in good yield and enantioselectivity (74–92% yield, 80–90% ee; Table 1, entries 1–4). With respect to the nucleophilic component, various aromatic groups can be installed under the same conditions in high yield and ee as well (83–93% yield, 86–92% ee; entries 5–8).
