Novel Cyclic Enaminone Esters and N-Heterocycles by Divergent Chemical Behavior through Amine-Mediated Reactions
(Wiley VCH Verlag, 2015-07)
New acridinones and enaminone esters were synthesized by microwave-assisted tandem-Michael-Michael addition and cyclization from cyclohexane-1,3-diones. The reaction mechanism for both open and closed structures, and the ...
A Facile, Versatile, and Mild Morita-Baylis-Hillman-Type Reaction for the Modular One-Pot Synthesis of Highly Functionalized MBH Adducts
(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 ...

Metallic chalcogenolates mediated modular Michael-aldol cascade reaction: an easy route to multi-functionalized chalcogenides and Morita-Baylis-Hillman adducts
(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 ...
Design and synthesis of angucyclinone 5-aza analogues
(GEORG THIEME VERLAG KG, 2006)
A highly efficient one-pot procedure for the synthesis of phenanthridine-1,7,10-triones from acylbenzoquinones and cyclic enaminones is reported. The cycloaddition reactions of these quinones with 1-trimethylsilyloxybutadiene ...
Catálise orgânica: planejamento, síntese e aplicações em reações orgânicas estereosseletivas
(Universidade Federal de São Paulo, 2015-08-21)
This work deals with the development of new Organocatalysts using 1,8-diaminoanthracene as a platform for the first time, and their application to the nitro-Michael reaction. The chemical structures of these Organocatalysts ...
Adições de Michael assimétricas na obtenção de naftoquinonas com potencial antitumoral
(Universidade Federal de Minas GeraisUFMG, 2017-08-02)
In this study the efficiency of organocatalysts derived from Cinchona alkaloid in Michael asymmetric reactions was evaluated. 2-Hydroxy-1,4-naphthoquinone was selected as Michael donor in reactions involving -bromonitroalkenes ...
