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.

The diketones (8) and (11), key intermediates for an biogenetically modelled synthesis of the ancistrocladus alkaloids, were each prepared in one step only, and transforned into the isoquinoline and naphthalene moieties of (1) and (2).
