Recently, the quest of Asymmetric Methodologies have emerged as one of the cornerstones of organic chemistry. The synthesis of complex scaffolds with multiple stereogenic centers has become an enormous challenge for organic chemists. In our research group, we aim to develop new asymmetric methodologies based in Organometallic chemistry and Organocatalysis.

Our research is focused on the development of new methodologies, design of new catalysts or catalytic systems, application of organocatalysis to the synthesis of natural or biologically interesting compounds and the study of the mechanism of organocatalytic reactions.

Synergistic catalysis: Highly diastereoselective benzoxazole addition to Morita–Baylis-Hillman carbonates

 

 

An expedited method has been developed for the diastereoselective synthesis of highly functionalized alkyl-azaarene systems with good yields and high diastereoselectivities (> 15:1 dr). The methodology includes a synergistic catalysis event involving organometallic (10 mol% AgOAc) activation of an alkyl azaarene and Lewis base (10 mol% DABCO) activation of a Morita–Baylis–Hillman carbonate. The structure and relative configuration of a representative product were confirmed by X-ray analysis

Expanding the Scope of the Organocatalytic Addition of Fluorobis(phenylsulfonyl)methane to Enals: Enantioselective Cascade Synthesis of Fluoroindane and Fluorochromanol Derivatives

Abstract

Thumbnail image of graphical abstract

Highly enantioselective cascade reactions for the synthesis of fluoroindanes and chromanols derivatives are described. The cascade reactions consisted of either a double Michael reaction or Michael–hemiacetal formation via the addition of fluorobis(phenylsulfonyl)methane (FBSM) to enals. The final products were obtained in good yields with excellent stereoselectivities.

November 2013: A New Review from our group is online:

Nucleophilic addition to carbon–nitrogen double bonds (imines) represents one of the most common strategies for the synthesis of amine derivatives. In order to circumvent the problem associated with low reactivity of imines in nucleophilic addition, various imines with electron-withdrawing groups at nitrogen have been studied, and many of them were successfully applied in asymmetric methodologies. Especially N-carbamoyl imines were found to be useful in the enantioselective synthesis of various organic compounds, due to their increased reactivity toward nucleophiles as well as limited difficulties connected with the removal of the carbamoyl moiety in target molecules. The aim of this review is to cover enantioselective methods based on N-carbamoyl imines, focusing on synthetically useful protocols.

Catalytic asymmetric one-pot synthesis of α-methylene-γ-lactams

An organocatalytic enantioselective synthesis of α-methylene-γ-lactams has been developed. The reaction between protected 2-aminomalonates and Morita–Baylis–Hillman carbonates is catalyzed by chiral Lewis bases to afford the corresponding lactams in excellent yields and moderate to good enantioselectivities, after work-up.
