Abstract: β-Alkoxycarbonyl-γ-lactams and γ-alkoxycarbonyl-δ-lactams were synthesized via a conjugate alkylation/Mannich reaction/lactamization tandem reaction of unsaturated dicarboxylates with diethyl zinc and aldimines. The high yield, the ready availability of the reagents, and especially the high diastereoselectivity are… read more here.
