A transition-metal-free one-pot procedure has been developed for the difunctionalization of alkynes by C-C triple bond oxidation and transformation towards chromone derivatives. This method involves cascade reactions for carbonylation of alkynes, base-promoted C-C & sigma;-bond cleavage, and intramolecular cyclization. It provides an efficient protocol for the synthesis of polysubstituted chromones from readily available starting materials.
