Preparation and cycloaddition of new imidazolinium ylides

This thesis contains the work performed on the preparation and cycloaddition of new dihydroimidazolium ylides. The work is organized as follows: Chapter 1 contains an introduction to imidazolines explaining their biological importance, their practical application and a review of synthetic methods for their generation and examples of their synthetic application. Chapter 2 contains a general review of the 1,3-dipolar cycloaddition reaction as an important and versatile tool for nitrogen heterocyclic compound generation. Particularly, it focuses on the components, mechanism, FMO and summarizes the well-established methods for azomethine ylide generation, and some examples of their use. [Continues.]
