One-pot synthesis of substituted 4H-chromenes by three-component reaction of alkyl isocyanides, dialkyl acetylenedicarboxylates, and N-aryl-3- hydroxynaphthalene-2-carboxamide

Hassanabadi, Alireza,Mosslemin, Mohammad H.,Anary-Abbasinejad, Mohammad,Ghasemi, Maryam

experimental part, p. 3714 - 3719 (2011/10/09)

The reactive intermediate generated by the reaction of alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by N-aryl-3-hydroxynaphthalene- 2-carboxamide for the preparation of substituted 4H-chromenes in good yields. Copyright Taylor & Francis Group, LLC.
