摘要
Polymer-supported sulphonic acid (NKC-9) efficiently catalyzed the cross-aldol condensation of arylaldehydes and cycloketones to afford alpha,alpha',-bis(substituted benzylidene) cycloalkanones in good yields. The catalyst can be recovered simply and reused. (c) 2007 Elsevier B.V. All rights reserved.
