Abstract

In the title compound, C21H20O3, the tolyl ring makes a dihedral angle of 31.11 (6)° with the benzene ring of the chromanone unit. The pyrone ring adopts a half-chair conformation. The mol­ecular structure is stabilized by a weak intra­molecular C—H⋯O inter­action and the crystal packing is stabilized by weak inter­molecular C—H⋯O inter­actions and a C—H⋯π inter­action
