In the title compound, C(12)H(15)NO(3), the ethoxy-benzyl ring plane forms a dihedral angle of 60.3 (4)° with the mean plane of the oxazolidine ring. The mol-ecules are linked through N-H⋯O hydrogen bonds into a chain running in the b direction.
In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.
The title compound, C(15)H(9)ClO(2), is a synthetic flavonoid obtained by the cyclization of 3-(4-chloro-phen-yl)-1-(2-hy-droxy-phen-yl)prop-2-en-1-one. The 4-chloro-phenyl ring is twisted at an angle of 11.54° with respect to the chromen-4-one skeleton. In the crystal, pairs of mol-ecules are inter-connected by weak Cl⋯Cl inter-actions [3.3089 (10) Å] forming dimmers which are further peripher...
