<jats:p>Stabilized sulfur ylide mediated cyclopropanation and formal [4+1] cycloaddition of 3‐acyl‐2<jats:italic>H</jats:italic>‐chromenones and their imines were explored. The transformations could be performed under mild conditions and were shown to have wide substrate scopes and significant functional‐group tolerance; furthermore, the reactions proceeded with excellent regioselectivity. Thus, they are powerful methods for the one‐pot synthesis of highly functionalized cyclopropane‐ and dihydropyrrole‐fused chromen‐2‐one derivatives.</jats:p>
