Mohammadi AA, Hadadzahmatkesh A, Asghariganjeh MR - Monatsh. Chem. (2011)

Bottom Line: FeNH4(SO4)2·12H2O (alum) efficiently catalyzes the one-pot three-component reaction of dimedone, aldehydes, and 3-aminocrotonate to afford 1,4-dihydropyridines.The work-up is easy, and the products are obtained in good to excellent yields and high purity.

Mentions: In continuation of our ongoing work on multi-component reactions (MCRs) [13–16], we now wish to report a facile and rapid one-pot three component reaction for preparation of DHP derivatives 4a–4k from dimedone 1, aldehydes 2a–2k, and 3-aminocrotonates 3a, 3b using non-toxic and readily available FeNH4(SO4)2·12H2O as heterogeneous catalyst (Scheme 1).
