Herein, we describe a [2 + 2] photocycloaddition of cyclopropenes bearing styryl group to prepare housane derivatives. The reaction occurs via selective excitation the styrene fragment, enabling completely stereoselective stepwise cycloaddition. Fused-housane derivatives with an unprecedented substitution pattern are prepared in simple manner using convenient visible light.
