Multicomponent approach to silica-grafted peptide catalysts : A 3 D continuous-flow organocatalytic system with on-line monitoring of conversion and stereo-selectivity
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 28/11/2014)The derivatization of organocatalysts with functional appendages suitable to anchor onto solid supports is usually achieved by stepwise syntheses. As an alternative to such a strategy, this work describes a one-pot approach ... -
Síntese de precursores de heterociclos e sistemas cíclicos nitrogenados
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 23/03/2018)β-halovinyl ketones are valuable and versatile synthetic intermediates for the synthesis of precious bioactive molecules. Majority of the already described methodologies for the synthesis of these versatile building blocks ... -
Synthesis of N-heterocycles and building blocks using multicomponent, photochemical and electrochemical approaches
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 17/02/2020)Multicomponent reactions and protocols mediated by light and electrochemistry are powerful tools for modern organic synthesis. Moreover, they obey several principles of green chemistry such as atom economy, catalysis, waste ... -
Sustainable synthesis of ciclopentene derivatives through multicomponent reactions in continuous flow regime
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Química - PPGQ, Câmpus São Carlos, 25/03/2020)Sustainable chemistry has gained relevance in recent years, not only in the fine chemical industry, but also in organic synthesis. This new conception of chemistry allows the development of environmentally friendly processes, ...
