Abstract
Multicomponent reactions involving 4-hydroxycumarine, activated acetylenic compounds and N-nucleophiles under solvent-free conditions were investigated. The reactions could also be extended to quinoline or CH-acides. Substituted chromen could be obtained from this routine, which may have potential applications in drugs fields.
Keywords: 4-Hydroxy coumarin, acetylenic compounds, isoquinoline, one-pot reactions, solvent-free.
