Alpha-Heterofunctionalized carbonyl compounds have a wide versatility as synthetic building blocks, due to a variety of transformations that these can participate. However, there are a limited number of asymmetric methodologies to prepare this class of compounds. Therefore, the development of such methodologies is of great importance in the area of organic synthesis. Combining this need w…
The expansion of products that can be obtained through the transformation of vegetal biomass has been a great challenge, especially in the case of complex molecules with high added value. In this case, it is important to develop new methodologies or synthetic transformations that can supply new compounds from raw materials that are easily obtained from the biomass in abundant form (levuli…
Subproject A: Synthesis of prochiral b-cetosulfoxonium ylides and its application in asymmetric insertion reactions catalyzed by gold. Subproject B: The use of Bronsted acids in the organocatalytic decomposition of diazo compounds in the presence of nucleophilic agents. (AU)

Cyclopropanes are extremely versatile as platforms for building organic molecules, since they have a high ring tension, being very reactive towards ring opening reactions. Sulfoxonium ylides can be used for these reactions, obtaining products of biological or synthetic interest. In this project we propose the use of chiral sulfoxonium ylides with the aim of carrying out the synthesis of c…
Polyurethanes (PUs) are one of the most important types of polymeric materials due to their applications in different fields of industrial chemistry because of their properties. Their main way of obtaining it is trough polyaddition reaction of isocyanates and polyols. The isocyanate monomers that are used as starting material are synthesized from toxic phosgene, therefore, several greener…
Sulfur ylides represent an important synthetic tool for organic chemists since they are used as building blocks in total synthesis, in the materials chemistry, and in the production of drugs, for example. However, there is a great difficulty associated with the alkylation of these compounds, mainly of the stabilized ones, as is the case of the ²-ketosulfoxonium ylides. For this reason, ob…
Sulfur ylides consist of a chemical class that is currently establishing itself as versatile substrates in organic synthesis. Its structural characteristics guarantee an ambiphilic character, allowing sulfur ylides to participate in reactions with different electrophiles and nucleophiles.Although the ²-keto sulfoxonium ylides have a wide range of synthetic applications, one of the less ex…
Polyurethanes are polymeric materials that have a wide range of applications in various fields due to their attractive and diverse properties. The main production of these polymers occurs through the polyaddition reaction between diisocyanates and polyols. Polyols are important monomers that, in addition to their applications in the polyurethane industry, are also used, for example, as an…
A great challenge for synthetic organic chemists is ensuring molecular diversity and structural complexity in reaction products, carried out by selective methodologies with a few number of steps. The development of synthetic approaches that provide enantiomerically enriched compounds have attracted a continuous interest from both academia and industry, since different enantiomers of an or…

Our research group has been advancing the sulfur ylides chemistry, exploring the reactivity of this compounds in a range of synthetic transformations. Currently, we are studying the reaction of sulfur ylides with highly reactive species, such as carbocations and strained-rings. In this sense, Prof. Dr. Edward Anderson at Oxford University has an extensive experience with strained-ring, de…
Our research group have been exploring the chemistry of sulfoxonium ylides and using these compounds in several relevant chemical transformations. Currently, we are studying the reactivity of these scaffold in the presence of diazo and hypervalent iodine. On this view, Prof. Dr. Graham Murphy at the University of Waterloo (Canada) has an extensive experience with hypervalent iodine reagen…
In recent years, sulfur ylides have received significant attention as equivalents of diazo compounds and as precursors of metal-carbene complexes. Although significative advances have been made regarding the use of a-carbonyl metal-carbenes as intermediates in organic synthesis, a less explored type of metal-carbene, containing a-imino group, still have limited sources and few general app…
Our research group have been exploring the chemistry of a,b-unsaturated diazoketones and b-ketosulfoxonium ylides and using these compounds in several relevant chemical transformations. Currently, we are studying enantioselective reactions employing a,b-unsaturated diazoketones, aryl and alkyl diazoketones and b-ketosulfoxonium ylides. In this project, enantioselective reactions will be d…
