چکیده
The title compound, C(13)H(17)NO(3), was synthesized from methyl 3-oxobutanoate and 4-ethoxy-benzenamine using a catalytic amount of InBr(3) under solvent-free conditions. The 3-amino-but-2-enoic acid methyl ester group is planar and forms a dihedral angle of 83.4 (1)° with the benzene ring. The eth-oxy group is slightly twisted away from the benzene ring [dihedral angle = 13.8 (1)°]. An intra-molecular N-H⋯O hydrogen bond generating an S(6) ring is observed. Mol-ecules are linked into a chain along the b axis by inter-molecular C-H⋯O hydrogen bonding.

The C=C bond in the title compound, C(15)H(15)NO(4)S, has a Z configuration. The thia-zolidine ring is essentially planar [maximum deviation = 0.008 (1) Å for the N atom] and is oriented at a dihedral angle of 59.1 (1)° with respect to the benzene ring. In the crystal, pairs of C-H⋯O hydrogen bonds link centrosymmetrically related mol-ecules into dimers, generating R(2) (2)(18) ring motifs. The...
