New electropolymerized chiral salen-chromium complexes have been successfully used as heterogeneous catalysts for the asymmetric hetero Diels-Alder reaction. These insoluble catalysts were reused up to six times affording, the expected products with unchanged enantioselectivity along the recycling procedure. Promising attempts to use these catalysts in a multi-substrate procedure are described. (c) 2007 Elsevier B.V. All rights reserved.
