Autor: Massimo Carraro, Camillo Are, Ugo Azzena, Lidia De Luca, Silvia Gaspa, Giuseppe Satta, Wolfgang Holzer, Vittorio Pace, Luisa Pisano
Publikováno v: Molecules, Vol 29, Iss 8, p 1714 (2024)
Aryl and heteroaryl iodides have been efficiently converted into the corresponding thioacetates in cyclopentyl methyl ether (CPME), a green solvent, under Cu catalysis. The chemoselectivity of the reaction is mainly controlled by electronic factors,

Application of Biobased Solvents in Asymmetric Catalysis
Autor: Margherita Miele, Veronica Pillari, Vittorio Pace, Andrés R. Alcántara, Gonzalo de Gonzalo
Publikováno v: Molecules, Vol 27, Iss 19, p 6701 (2022)
The necessity of more sustainable conditions that follow the twelve principles of Green Chemistry have pushed researchers to the development of novel reagents, catalysts and solvents for greener asymmetric methodologies. Solvents are in general a fun

Synthesis of tetrasubstituted pyrazoles containing pyridinyl substituents
Autor: Josef Jansa, Ramona Schmidt, Ashenafi Damtew Mamuye, Laura Castoldi, Alexander Roller, Vittorio Pace, Wolfgang Holzer
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 13, Iss 1, Pp 895-902 (2017)
A synthesis of tetrasubstituted pyrazoles containing two, three or four pyridinyl substituents is described. Hence, the reaction of 1,3-dipyridinyl-1,3-propanediones with 2-hydrazinopyridine or phenylhydrazine, respectively, affords the corresponding

Synthesis, computational investigation and biological evaluation of α,α-difluoromethyl ketones embodying pyrazole and isoxazole nuclei as COX inhibitors
Autor: Andrea Citarella, Laura Ielo, Claudio Stagno, Mariateresa Cristani, Claudia Muscarà, Vittorio Pace, Nicola Micale
Publikováno v: Organic & Biomolecular Chemistry. 20:8293-8304
α,α-Difluoromethyl ketones (DFMKs) have emerged as currently investigated agents benefiting from the merging of chemico-physical features conferred by the constitutive elements (-CHFsub2/suband carbonyl moietites). With a view to biological applica
