This volume focuses on the chemistry of dienes and polyenes, which are an extremely important group of chemicals in the investigation of different types of syntheses based on the Diels-Adler reactions that allows for stereospecific molecules to be prepared. Dienes and polyenes are found in a large number of natural and human-made products, including such natural products as terpenes, cholesterol, Vitamin A, and many essential oils, as well as many polymers and rubber products.
