Controlled vinylogous carbon–carbon bond-forming reactions are useful options for providing the selective remote functionalization of conjugated carbonyl substrates. Remotely enolizable alkylidene heterocyclic and carbocyclic carbonyl compounds are pro-nucleophilic substrates that may be engaged in highly valuable chemical transformations. This review emphasizes the merits of these recently discovered vinylogous donors in the chemo-, regio- and stereoselective synthesis of many functionality-rich products.1 Introduction2 Alkylidene Oxindoles3 Alkylidene Pyrazolinones4 Alkylidene Furanones5 Alkylidene Azlactones6 Cycloalkylidene Carbonyl Compounds7 Alkylidene Indenones8 Cycloalkylidene Malononitriles9 Conclusion
Three-component carbon-carbon bond-forming reactions for the synthesis of β-amino carbonyl compounds using maleic acid-catalyzed one-pot mannich-type reaction in ethanol
