The reactions of 2-cyano-3-ferrocenylacrylonitrile (1) with malononitrile (2) in a MeOH/H 2 O or 2-PrOH/H 2 O medium in the presence of Na 2 CO 3 afforded 6-alkoxy-2amino-4-ferrocenylpyridine-3,5-dicarbonitriles 3a,b (multi-component condensation) and 6-alkoxy-2-amino-4-ferrocenyl-3-ferrocenylmethyl-3,4-dihydropyridine-3,5-dicarbonitriles 4a,b (multi-component cyclodimerization). Analogous reactions of 1 with 2 in an MeOH/H 2 O medium in the presence of NaOH, piperidine, or morpholine gavedoi:10.3390/molecules170910079 pmid:22922279 fatcat:c4kkwtvsqzb7hddba5ix6sfp3q
