The conjugate addition of activated nitrogen nucleophiles, such as hydroxylamine and hydrazine derivatives, to α, β-unsaturated bicyclic lactam 1a gave the corresponding β-amino products 9a-g in good yield and excellent diastereo- selectivity. These products can be manipulated to afford enantiopure β-aminopyrrolidinones of potential application as conformationally-constrained, substituted glutamate templates of well-defined stereochemistry.

The conjugate addition of nitrogen nucleophiles to α,β-unsaturated lactam 1b under very mild conditions occurs in good yield with high diastereoselectivity. Deprotection provides a simple access to β-aminopyrrolidinones in excellent overall yield.
