摘要：

And aryne makes three: The three-component coupling of arynes, DMF, and active methylenes has provided an efficient method for the synthesis of 2H-chromene and coumarin derivatives (see scheme). The sequential multistep reactions are driven by the release of strain energy in the arynes and intermediates, and this finding was supported by thermodynamics.
