Metallic chalcogenolates mediated modular Michael-aldol cascade reaction: an easy route to multi-functionalized chalcogenides and Morita-Baylis-Hillman adducts

Sousa, Bruno A.; Keppler, Arthur F.; Gariani, Rogerio A.; Comasseto, Joao V.; Dos Santos, Alcindo A. (PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)

Chalcogenolate mediated Michael-aldol cascade reactions consists of a very efficient route to multi-functionalized gamma-hydroxichalcogenides. Although, when selenolates are employed, these gamma-hydroxichalcogenides can ...

A Facile, Versatile, and Mild Morita-Baylis-Hillman-Type Reaction for the Modular One-Pot Synthesis of Highly Functionalized MBH Adducts

Sousa, Bruno A.; Santos, Alcindo Aparecido dos (Wiley-V C H Verlag GmbHWEINHEIM, 2012)

MoritaBaylisHillman derivatives have been extensively investigated as intermediates in the preparation of important classes of compounds. However, there are intrinsic limitations regarding the structure of the Michael ...

Structural diversity and similar bioactivity in synthetic bicyclononanes

Luna, Liliana Edith; Forastieri, Pamela Soledad; Marchiaro, Patricia; Limansky, Adriana Sara; Cravero, Raquel Maria (Taylor & Francis, 2016-03)

Simple syntheses of diverse bicyclo[3.3.1]nonanes and related compounds as the minimal substructure of bioactive natural products via Michael, aldol, and alkylation reactions from diketones are described herein. The ...

Synthesis of benzylidenecycloalkan-1-ones and 1,5-diketones under Claisen–Schmidt reaction: Influence of the temperature and electronic nature of arylaldehydes

Lantaño, Beatriz; Aguirre, José M.; Drago, Eleonora V.; Bollini, Mariela; de la Faba, Diego J.; Mufato, Jorge Domingo (Taylor & Francis, 2017-12)

Herein, we present the results of the influence of reaction temperature and the electronic nature of arylaldehydes in the reactions of benzocycloalkan-1-ones and arylaldehydes under classical Claisen–Schmidt condensation ...

Lithium butylchalcogenolate induced Michael-aldol tandem sequence: easy and rapid access to highly functionalized organochalcogenides and unsaturated compounds

KEPPLER, Artur F.; GARIANI, Rogerio A.; LOPES, Danilo G.; COMASSETO, Joao V. (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

Lithium ""butylchalcogenolates are generated in situ by reacting the elements (S, Se, and Te) with (n)butyl-lithium at 0 degrees C. Reaction of the lithium alkylchalcogenolates with activated alkenes and aldehydes gives ...
