Abstract:
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.

When a substrate with two different β hydrogens undergoes an E2 elimination, the presence of a strong base can yield two regioisomeric alkenes. The more-substituted alkene is the major product and...
Isomerism in Alkenes
An isomer is called cis-2-butene when the methyl groups are on the same side of the double bond, and the other stereoisomer, in which methyl groups are on the opposite side of the double bond, is called trans-2-butene. The cis and trans stereoisomers are not...
