Abstract

In the title compound, C17H18O3, the two non-spiro C atoms of the cyclopropane ring bear a formyl and a phenyl substituent which are trans-oriented. In the crystal, molecules are linked by weak C-H center dot center dot center dot O and C-H center dot center dot center dot pi contacts resulting in a three-dimensional supramolecular structure.
