The acid-controlled single-component retro-aldol/Michael addition cascade reaction and [4 + 2] cycloaddition of benzofuran-derived azadienes (BDAs) are reported for the first time. Under conditions trifluoromethanesulfonic acid as catalyst with water, BDAs initiate retro-aldol reaction, followed by a 1,4-Michael addition, yielding (arylmethylene)bis(dibenzofuran) products excellent yields broad substrate applicability. This represents application in reaction. In contrast, absence water boron trifluoride etherate catalyst, undergo constructing spiro[benzofuran-2,3'-benzofuro[3,2-b]pyridine] framework high diastereoselectivity. method features mild atom economy, provides new approach benzofuran scaffold derivatives.
