New insights into the chemistry of gem-bis(phosphonates): Unexpected rearrangement of Michael-type acceptors
(Wiley VCH Verlag, 2005-08)
The use of tetraethyl ethylidenebis(phosphonate) as a Michael acceptor with different nucleophiles was investigated. It was found that in some cases this compound undergoes phosphate removal, depending on the nature of 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 ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2008-08-01)
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 ...
New polyfunctional dendritic linear hybrids from terminal amine polyether oligomers (Jeffamine®): Synthesis and characterization
(Pergamon-Elsevier Science Ltd., 2005-04)
New dendritic polyether oligomers were synthesized from three different Jeffamines® and characterized. This class of polyfunctional oligomers, bearing on their surface methylester, carboxylic acid, nitrile or amine groups, ...
Flow Chemistry: From assembly to the application
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-12-17)
Over the centuries, chemical reactions have been carried out in the same way in standardized glassware. On the other hand, continuous flow reactions are gaining interest regularly and demand for the related hardware toolkit ...

The development of a fluorescence turn-on sensor for cysteine, glutathione and other biothiols. A kinetic study
(Elsevier, 2011)
Two fluorescence probes for the detection of cysteine (Cys), glutathione (GSH) and other biothiols, such as homocysteine (Hcy) and cysteinyl-glycine (Cys-Gly), were developed. These molecular probes are coumarin-based ...
