Switching Dual Catalysis without Molecular Switch: Using A Multicomponent Information System for Reversible Reconfiguration of Catalytic Machinery
Goswami, Abir,Paululat, Thomas,Schmittel, Michael
, p. 15656 - 15663 (2019)
Different from the current paradigms of chemistry, a switchable catalytic system is presented that does not rely on a molecular switch in different toggling states but on a smart seven-component mixture that manages the reversible ON/OFF regulation of two

A novel 1,3-bis(4-fluorophenylthio)-propane ligand based CuI 1-D polymeric coordination complex having formula ([(CuI)2{ArS(CH2)3SAr}2]n, Ar = 4-F-C6H4) has been synthesized and characterized by 1H NMR, 13C NMR and single crystal XRD techniques. This complex has been employed for the first time as suitable catalyst for base-free one-pot three-component regioselective azide-alkyne cycloaddition (AAC) reaction. A novel 1,2,3-triazole compound with sulfur functionalized pendant arms has also been prepared using our catalytic system in a multicomponent manner via one-pot two-step reaction.

In this manuscript we describe synthesis and cytotoxicity evaluation of some triazolic derivatives against B16 melanoma cell line. For this purpose, we transformed a set of aromatic aldehydes into terminal alkynes, using Besthmann-Ohira reagent, and we made the corresponding hydroxymethyl homologated alkynes by an acetylene Grignard reagent. These generated two sets of alkynes were then subjected to a copper(I)-catalyzed alkyne-azide cycloaddition reaction (CuAAC) using a solid-supported catalyst (Amberlyst A-21?CuI), with a third set composed of organic azides. Synthesized triazoles were then tested in?vitro against B16 melanoma cell line. Amongst them, compounds a1b1 (R1?=?p-nitrophenyl, R2?=?benzyl), a4b1 (R1?=?naphthyl, R2?=?benzyl) and a4b5 (R1?=?naphthyl, R2?=?(R/S)- dioxolane) showed the best activity against B16 melanoma cells, with IC50of 5.12, 3.89 and 6.60?μM respectively.
Nano-magnetic-iron Oxides@choline Acetate as a Heterogeneous Catalyst for the Synthesis of 1,2,3-Triazoles
Heydari, Akbar,Mohammadkhani, Abolfazl
, (2021/08/09)
In this research, four cholines supported on core–shell iron oxides, Fe2O3@MgO@Ch.OAc (choline acetate), Fe2O3@MgO@Ch.OH (choline hydroxide), Fe3O4@Ch.OAc, Fe3O4@Ch.OH, were synthesized. The synthesized catalysts were tested in 1,2,3-triazoles synthesis by the reaction of nitromethane, aldehyde, and benzyl azide in EtOH as a green solvent. Among four synthesized heterogeneous catalysts, the Fe2O3@MgO@ch.OAc showed superior catalytic activity for the reaction and afforded the desired triazoles in good isolated yields under mild reaction conditions.
