When it comes to organic chemistry and the synthesis of specific products there is an abundant amount of routes that can be taken and still get you the same result. For the following experiment‚ the main focus is the use of a cycloaddition reaction‚ also known as Diels-Alder. According to the lab manual‚ this reaction consists of the addition of a diene and a dienophile and that the Diels-Alder reaction builds stereospecific ring compounds with ease (Weldegirma 80). The reaction takes place between
