Microwave Assisted Three Component Reaction Conditions to Obtain New Thiazolidinones with Different Heterocyclic Skeletons

Autor: Fernando J. Lorenzo, Romina Andrea Ocampo, Sandra D. Mandolesi

Publikováno v: The 23rd International Electronic Conference on Synthetic Organic Chemistry.

Taking into account previous results studied in our research group in the synthesis of 4-thiazolidinones selectively by a three-component reaction, we present here a new proposal for the “one pot” generation of new 4-thiazolidinones through a mul

Application of Didactic Strategies as Multisensory Teaching Tools in Organic Chemistry Practices for Students with Visual Disabilities

Autor: Gabriela Araceli Fernandez, Romina Andrea Ocampo, Néstor S. Dop, Andrea Costantino

Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learnin

The synthesis of C2 symmetry diesters of (3R,4R)-TTFOL through a green and stereoselective (2R,3R)-TADDOL rearrangement

Autor: Romina Andrea Ocampo, Andrea Costantino, Sandra D. Mandolesi, Liliana C. Koll, Antonio Galdámez, María Gabriela Montiel Schneider

Publikováno v: Tetrahedron: Asymmetry. 26:1341-1347

An efficient, green, and atom economic methodology for the stereoselective synthesis of C2 symmetry (3R,4R)-TTFOL diester derivatives has been developed. The procedure occurs through a (2R,3R)-TADDOL dioxolane cleavage and rearrangement under mild co

Publikováno v: Proceedings of The 21st International Electronic Conference on Synthetic Organic Chemistry.

In previous studies of our research group, we have selectively generated a pool of new 4-thiazolidinones by three-component reaction, solvent-free and microwave-assisted, between an aldehyde derived from a carbohydrate, a heteroaromatic amine and thi

Publikováno v: Proceedings of The 17th International Electronic Conference on Synthetic Organic Chemistry.

The aim of this work is the synthesis of some BINOL derivatives due to their catalytic, biological and medicinal activity. The rigid structure, thermal stability and the C2 symmetry of the binaphthyl molecules play an important rol in asymmetric indu
