The structure of the given compound and the mechanism of the given reaction are to be determined. Concept introduction: 1 H NMR (hydrogen nuclear magnetic resonance) is an analytical technique in chemistry to determine the purity and molecular structure of a compound. 13 C NMR, or the carbon- 13 nuclear magnetic resonance, is an analytical technique in chemistry to identify the carbon atoms in the structure of a compound. It is an important tool in structure elucidation of organic compounds. However, it can only detect the C 13 isotope, and not C 12 , as the latter has zero net spins. To determine the actual structure of organic compounds, IR spectroscopy (Infrared spectroscopy) is an invaluable tool. The use of electromagnetic radiation is involved in IR spectroscopy with frequencies ranging from 4000 − 400 cm − 1 . Transesterification is a process in which the R group of an ester is exchanged with an R group of an alcohol. This process takes place in the presence of a base catalyst or an acid catalyst.

O aldehydes are more reactive toward nucleophiles than ketones. Onucleophilic attack occurs preferentially at the less hindered carbon of the formyl group.

Gamma(y)-amino butyric acid (GABA) is a neurotransmitter (a chemical that is used to send signals from one neuron to another) of the mammalian central nervous system. In order to understand how GABA works, conformationally restricted analogues, such as compound 1, have been made. During a synthesis of compound 1, compound 2 was subjected to allylic bromination using NBS and a radical initiator (AIBN) instead of light (Aust. J. Chem. 1981, 34, 2231-2236). H₂N.
