Abstract:

The Diels Alder (D-A) reaction represents a crucial component of fundamental organic chemistry education and serves as a quintessential example of structural chemistry analyzed via basic principles of chemical sciences. This study explores the Diels-Alder reaction involving 1-methoxy-1,3-butadiene and acrolein, utilizing tools such as the Hückel molecular orbital (HMO) method, frontier molecular orbital (FMO) theory, and quantum chemical calculations. This approach provides detailed quantitative data and intuitive visual illustrations to elucidate the stereospecificity, regioselectivity, and stereoselectivity inherent to this reaction. The findings from this study serve as valuable resources for students, not only enhancing their understanding of D-A reaction properties and principles, but also developing their interest in computational chemistry and augmenting their problem-solving acumen.

Key words: Diels-Alder reaction, Stereospecificity, Regioselectivity, Stereoselectivity, DFT calculations
