Pyrrole-based silyl dienolates undergo asymmetric vinylogous Mukaiyama Mannich reactions with a series of N-aryl aldimines in the presence of the Hoveyda-Snapper amino acid-derived silver(I) catalysts. The Mannich products-α,β-unsaturated δ-amino-γ-butyrolactams-are typically obtained in high yields, excellent γ-site selectivities and anti-diastereoselectivities, and up to 80% enantioselectivity.
