In the title chiral butterfly-like bicyclic lactam, C(14)H(15)NO(3), the phenyl and methyl groups are syn with respect to each other. The dihydro-pyrrrole ring adopts a boat conformation, whereas the oxazole ring has a slightly distorted boat conformation. The packing of mol-ecules in the crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
