SOLVENT-FREE MICROWAVE MICHAEL ADDITION OF ISATIN AND ANILINE SCHIFF BASE OF ISATIN TO α,β-UNSATURATED ESTERS
(Sociedad Chilena de Química, 2011)
Solvent-free microwave synthesis of 3-(4-benzo[b]thiophene-2-carbonyl)-1-piperazinyl-1-benzo[b]thiophen-2-yl-1-propanones. New hetero bis-ligands with potential 5-HT1A serotonergic activity
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A novel series of 2-benzothiophenealkylpiperazine derivatives 11 (a-d) with potential affinity at 5-HT1A serotonin receptors have been synthesized via solvent-free, microwave-promoted Michael addition of benzo[b]thiophene ...
Diastereoselective addition of nitro compounds to alpha,beta-unsaturated gamma-butyrolactones
(Pergamon-elsevier Science LtdOxfordInglaterra, 2006)
Multicomponent combinatorial synthesis of proplyl peptide-lipopeptoid hybrid catalyst: application in the asymmetric Michael addition under aqueous environment
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-11-29)
This study describes the synthesis of a new library of prolyl peptides-lipopeptoid hybrids catalysts through a multicomponent combinatorial approach. For the design of this catalyst library, we took into consideration the ...
Solvent-free microwave-promoted Michael addition of azanucleophiles to benzo[b]thiophen-2-yl-2-propenone
(Arkat, 2009)
A series of Michael adducts (5-11) have been synthesized with good yields under solvent-free microwave conditions. Aliphatic and aromatic amines utilized as Michael donors reacted with 1-(4,7-dimethoxybenzo[b]thiophen-2- ...
Anti-Selective Organocatalytic Michael Addition between Phenylacetaldehyde and Nitrostyrene
(American Chemical Society, 2016-09)
Using the reaction between phenylacetaldehyde and nitrostyrene catalyzed by pyrrolidine as a simple model, we have studied the diastereochemical outcome of the organocatalytic Michael reactions between benzylic aldehydes ...
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 ...
In situ generation of n-butanethiol and its reaction with electron-deficient olefines
(TAYLOR & FRANCIS INC, 2008)
n-Butanethiol is generated in situ by sequential addition of n-butyllithium and water to elemental sulfur. The n-butanethiol formed was reacted with electron-deficient olefines to give Michael-type addition products in ...
Quantitative characterization of the global philicity patterns of common diene/dienophile pairs in cycloaddition reactions II: the interacting pair model
(Elsevier, 2015)
We present a unified model of electrophilicity and nucleophilicity that considers the electrophile/nucleophile
pair in an interacting regime, thereby avoiding the arbitrariness of defining them as the opposite
ends of a ...
