Regioselectivity of Diels-Alder Reactions Between 6,7-Dehydrobenzofuran and 2-Substituted Furans.

ABSTRACT: We describe the first report of the generation of 6,7-dehydrobenzofuran (6,7-benzofuranyne) from 6,7-dihalobenzofurans via metal-halogen exchange and elimination, in a manner similar to our previous work with 6,7-indole arynes. This benzofuranyne undergoes highly regioselective Diels-Alder cycloadditions with 2-substituted furans.
