A recyclable fluorous organocatalyst for Diels-Alder reactions

摘要

Chiral fluorous imidazolidinone catalyst >2 provides consistently high enantioselectivities in Diels-Alder reactions of dienes and α, β-unsaturated aldehydes. The catalyst can be readily separated from the reaction products by fluorous solid-phase extraction, and recovered in excellent purity for direct reuse.
