Abstract
The trapping reaction of the transient intermediate ortho-quinone methides, generated by the insertion of arynes into a carbon-oxygen double bond of DMF, with dienophiles was investigated. The [4+2] cycloaddition products were obtained when the diesters of acetylenedicarboxylic acid were employed as dienophiles.
