Studies Directed Towards The Iridium Catalyzed Synthesis Of New Carbon-Nitrogen Bonds., Maria Lindsay

University of New Orleans Theses and Dissertations

Amines are ubiquitous in nature and serve a variety of functions in living organisms. Because of this fact amines are of great biological and pharmaceutical interest. The iridium catalyst (pentamethylcyclopentadienyl) iridium dichloride dimer ([Cp*IrCl₂]₂) has been used in a number of ways to synthesize new carbon-nitrogen bonds. These studies were directed toward the development of a method for the iridium catalyzed N-alkylation of alpha-amino acid esters as well as the development of a strategy for synthesis of the natural product 275A.

We have optimized a method for the N-alkylation for alpha-amino acid esters. Using this …

Design, Synthesis And Glioblastoma Activity Of 1,3-Diazinane Based Aryl Amides And Benzo Fused Heterocycles, Rebecca Hron

University of New Orleans Theses and Dissertations

The development of novel targeted therapeutics for the treatment of cancer remains difficult due to the complex nature of the disease itself as well as the challenges associated with the synthesis of these therapeutics. Impediments to the discovery of novel drug candidates include lack of available starting materials and access to well-developed syntheses which are both convenient and economically feasible. Semicarbazides, for instance, are a critical synthon for the manufacture of numerous biologically important molecules. Historically, convenient methods for the synthesis of semicarbazides and their derivatives did not exist. Recently, a facile and efficient method for the preparation of semicarbazides …
