Abstract

Diels‐Alder reactions of N‐functionalized acryloyl α‐pyrrolidone derivatives were investigated, which were catalyzed by FeCl~3~·6H~2~O as an efficient catalyst under solvent‐free conditions at room temperature. The corresponding cycloadducts with functionalized‐pyrrolidone were prepared in high yield with high stereoselectivity by a green chemistry procedure. N‐Functionalized acryloyl pyrrolidone derivatives, a kind of pyrrolidone‐functionalized chelating α,β‐unsaturated ketone usable as a dienophile in Diels‐Alder reaction, were synthesized by N‐acylation procedure in ionic liquid as a novel synthetic method.
