Most of the different homogeneous reactions catalyzed by gold have been developed in the past fifteen years and stem from the ability of both Au(I) and Au(III) complexes to coordinate and activate multiple carbon-carbon ...
Enzymes are the most efficient biocatalysts in Nature. However, biocatalysts in general are not capable of catalyzing reactions for industrial purposes. Hence, biocatalysts need to be engineered by introducing mutations ...
Metalloenzymes are a fundamental source of inspiration for synthetic chemists. Oxidation metalloenzymes catalyze oxidation reactions with high efficiency under very mild experimental conditions exhibiting exquisite regio- ...
The oxidation of hydrocarbons under soft and selective conditions is a reaction almost exclusively produced under these conditions by enzymes. A lot of these enzymes, posses iron in their metal center, responsible for the ...
In the last decades, carbenes have shown a huge potential and versatility in organometallic and organic chemistry. In each of these fields, first row transition metal chemistry is less developed than noble metal complexes. ...
During the last decades, computational chemistry has become a resourceful tool in the quest to understand and predict the mechanism and the reactivity of chemical systems. This is especially true in the area of ...
Fullerenes are a group of spherical molecules with outstanding 2/1 physicochemical properties that make them important materials in a variety of fields, ranging from biomedicine to photovoltaics. However, in order ...
The use of self-assembly to bring simple building blocks together into complex product, has led to the preparation of an increasing number of sophisticated and functional 3D supramolecular nanocapsules. By understanding ...
Selective oxidation of C-H bonds is an important reaction, as it can disclose novel synthetic strategies to get functionalized products through efficient paths. Nonetheless, due to the inert character of C-H bonds, the use ...
Enzymes are sophisticated biomacromolecules whose function is linked to its three-dimensional structure and conformational dynamics. Therefore, the understanding of enzyme conformational dynamics can be exploited to ...
Given the existing problem of Climate Change, we must work towards more environmentally friendly chemical processes that would help us solve it. The thesis focuses on the study of different chemical reactions involved in ...
In this thesis we developed a protocol for the intramolecular oxidation of prochiral secondary C-H bonds in which carboxylic acids, acting as directing groups for the oxidant species, promoted a highly site-selective and ...
The oxidative activation of C(sp3)–H bonds under ambient conditions represents a challenge to modern chemistry, nevertheless it is commonly operated in Nature by various oxygenases in key metabolic transformation and ...
Nowadays, one of the main goals in organic chemistry and fine industry is the development of new synthetic methodologies for the preparation of life-relevant products in a sustainable manner. The use of first-row ...
Chiral 1,2-amino alcohols are motifs widely present in different high valuable biologically active compounds. Many synthetic and enzymatic routes have been developed for producing optically active amino alcohols starting ...
The development of supramolecular assemblies with big cavities is important to recognize specific guests or infer a chemo- or regioselective chemistry, in analogy to natural enzymes. The objective of this thesis was to ...
Enzymes have evolved through years until becoming great catalysts that present high selectivity, specificity, and activity. Initially, enzymes were understood as static (bio)molecular structures capable of accelerating ...
In the last decades, electronic structure methods have been crucial for chemists to achieve deeper insight into chemistry itself and to make predictions before performing the actual experiments. The development of computational ...
The development of novel catalytic methodologies involving the formation of carbon – carbon/heteroatom bonds to produce cyclic systems constitutes a field of great interest in the modern synthetic organic chemistry. Over ...
Enzymes are molecules that play a crucial role in many biological and chemical processes. To understand how they work and how to design enzymes with specific functions, it is important to study their molecular structure ...
