In the title compound, C19H24O4, the six-membered lactone ring adopts an envelope conformation with the tert-butoxycarbonyl and isopropyl substituents in axial positions, and the phenyl group in an equatorial position. In the crystal structure, weak intermolecular C—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers.
