Abstract
-mediated [2 + 1] cycloaddition of benzofuran-derived azadienes (BDAs) with bromomalonate by using a dearomatization strategy has been developed. Through this process, BDAs serve as a potential 2-atom synthon in the construction of a range of functionalized spirocyclopropane derivatives, such as spirobenzofuran-2-cyclopropanes and spiroindane-2-cyclopropanes.
