The 10 alpha,20 beta-bis(4-nitrophenyl)-calix[4]pyrrole was found to act as an effective organocatalyst for the hetero Diets-Alder reaction of Danishefsky's diene with aromatic aldehydes. This discovery is the first reported case of a calixpyrrole that exhibits organocatalytic activity. (c) 2007 Elsevier Ltd. All rights reserved.
