In the highly competitive field of organocatalysis, we thought about developing something new and original. Being inspired by the organocatalyzed addition of carbonyl compounds to β-nitrostyrene we investigated a new type of nucleophile (donor) and a new type of electrophiles (acceptors). Therefore, in this thesis research, a huge effort has been devoted to the development of useful adducts which could be further transformed into interesting building blocks of high molecular complexity. As a result, organocatalysis combined with another synthetic transformation appears to become a new powerful tool that could be used in total synthesis.
