Abstract
The addition of a series of organocopper (alkyl, vinyl, allyl, and ethynyl) reagents to 3-acyl-N-alkylpyridinium salts, followed by acylation of the i ntermediate 1,4- or 1,2-dihydropyridines with trichloroacetic anhydride has been studied. (C) 2001 Elsevier Science Ltd. All rights reserved.
