tert-Butyl 4-isopropyl-2-oxo-6-phenyl-3,4-dihydro-2H-pyran-3-carboxyl­ate

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
