tert-Butyl 6-methyl-2-oxo-4-[4-(trifluoromethoxy)anilino]cyclohex-3-ene-1-carboxylate

Abstract

In the title compound, C19H22F3NO4, the dihedral angle between the benzene ring and the conjugated part of the enaminone ring is 42.5 (1)°. The ester substituent makes a dihedral angle of 81.3 (2)° with this latter moiety. The crystal structure is held together by strong N—H...O and weak C—H...O intermolecular interactions. The enaminone ring is disordered over two orientations with relative occupancies of 0.794 (4) and 0.206 (4).
