Herein, we present a palladium-catalyzed tandem [4+1] cycloadditions of vinyl benzoxazinanones with N-tosylhydrazones. The cycloaddition is accomplished by merging the in situ generated aza-ortho-quinone methides (aza-o-QMs) with nucleophilic carbenes. This method enables the construction of diverse indolines with broad functional group compatibility in good yields with high levels of diastereoselectivity under mild conditions.
