An efficient green-chemistry synthesis of conjugated polyenals from alpha,beta-enals, orthoesters, and alkyl vinyl ethers promoted by acidic ionic liquid [emim][HSO4] is described. The ionic liquid can be reused at least three times without any decrease in product yields. (C) 2010 Elsevier Ltd. All rights reserved.
