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 alpha,beta-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. (c) 2006 Elsevier Ltd. All rights reserved.
