Efficient Synthesis of 5-Chalcogenyl-1,3-oxazin-2-ones by Chalcogen-Mediated Yne Carbamate Cyclisation: An Experimental and Theoretical Study

Monleón, Alicia; Blay, Gonzalo; Domingo, Luis R.; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley-VCH Verlag, 2015-02)

A very efficient synthesis of 5-chalcogenyl-1,3-oxazin-2-ones has been accomplished by the chalcogen-mediated yne-carbamate cyclisation of chiral, non-racemic N-Cbz-protected propargylic amines using PhXY (X = Se, S, Te; ...
Gold Catalysis Opens Up a New Route for the Synthesis of Benzimidazoylquinoxaline Derivatives from Biomass Derived Products (Glycerol)

Climent Olmedo, María José; Corma Canós, Avelino; Iborra Chornet, Sara; Martínez Silvestre, Sergio (Wiley-VCH Verlag, 2013-12)

Process intensification by using well-defined solid catalysts able to perform one-pot multistep reactions is one of the open fronts in heterogeneous catalysis. This is even more relevant if new, more efficient synthesis ...
Ketone Formation from Carboxylic Acids by Ketonic Decarboxylation: The Exceptional Case of the Tertiary Carboxylic Acids

Oliver-Tomás, Borja; Renz, Michael; Corma Canós, Avelino (John Wiley & Sons, 2017-09-18)

[EN] For the reaction mechanism of the ketonic decarboxylation of two carboxylic acids, a -keto acid is favored as key intermediate in many experimental and theoretical studies. Hydrogen atoms in the -position are an ...
