In the second part, the preparation of oxygen precursors and its cyclization are studied.

CISQ: Centro de Investigación en Síntesis Química

In chapter 3, there is an introduction about enantioselective syntheses using chiral titanocene catalysts. The results and discussion section deals with the enantioselective cyclization of some of the precursors previously prepared using precatalyst R,R -ethylenebis heterociclos nitrogenados tetrahydroindenyl heterociclos nitrogenados IValso known as Brintzinger complex.

This chapter is also divided in an introduction, in which a review about the different methods of synthesis of stemoamide are included, and results and discussion. A review about the different [TiCp2Cl] catalyzed or promoted reactions reported to date, is included. Chapter 2 is divided in introduction and heterociclos nitrogenados and discussion.

Results and discussion section is sub-divided in other two parts.

The first one describes the synthesis of carbocyclic or nitrogen heterocyclic precursors bearing a propargyl halide and a carbonyl group. Resistance to at least heterociclos nitrogenados different antibiotics classes is very common, which restricts the available therapeutic options Schneider et al.

Pseudomonas aeruginosa is characterized by a Gram-negative rod, heterociclos nitrogenados a wide variety of plant and animal hosts Wu et al.

In humans, it is responsible for heterociclos nitrogenados lung infections affecting immunocompromised patients and also patients with cystic fibrosis Lyczak et al.

Widespread and careless use of antibiotics has led to a series of problems, among them, human ecology unbalance and microbial resistance, demanding a search for more efficient drugs to combat them. The development of any new antimicrobial drug is accompanied by microorganisms resistance, and their emergence is a threat to research advances Lyczak heterociclos nitrogenados al.

Due to the large raise of pathogenic microorganisms resistance to multiple drugs, there is a concern heterociclos nitrogenados finding new therapeutic alternatives Oliveira et heterociclos nitrogenados.

For patients, antimicrobial resistance augments morbidity, while for health institutions it corresponds to higher costs Dancer, [ 12 ].


According to Montanari [ 19 ]molecular modification is the most used method heterociclos nitrogenados obtain new drugs. It consists, basically, in heterociclos nitrogenados with a well characterized molecule, with known biological action, as a model or prototype, from which new compounds will be synthesized.

The chapter is divided in introduction and results and discussion.


In the introduction the different methodologies for the heterociclos nitrogenados of titanocene derivatives are reviewed. This section also includes the background in which this project is based. Chapter 6 includes the experimental part.
