Solution- and Solid-Phase Synthesis of Tetrahydroquinoline-Based Polycyclics Having α,β-Unsaturated γ-Lactam and δ-Lactone Functionalities

Abstract

With the goal of the library generation using the tetrahydroquinoline-based derivative, a simple and practical enantioselective synthesis of the tetrahydroquinoline derivatives having α,β-unsaturated γ-lactam and δ-lactone functional groups was achieved. The phenolic hydroxy group in the α,β-unsaturated γ-lactam was utilized as an anchoring site for the solid-phase synthesis. The ring-closing metathesis approach yielded the desired tricyclic products on the solid phase.

Key words

lactams - lactones - fused-ring systems - heterocycles - asymmetric synthesis - solid-phase synthesis
