Characterization and Application of Cyrene as a Biomass‐Based Solvent for Homogeneous Heck‐Coupling Reaction

ChemPlusChem, Journal Year: 2024, Volume and Issue: 89(11)

Published: July 9, 2024

Abstract Cyrene, a renewable, non‐toxic substance having negligible vapor pressure, even at high temperatures, was proposed as reaction medium for homogeneous Pd‐catalyzed Heck‐coupling reactions. It first characterized by its temperature‐dependent physicochemical properties, i. e., density, surface tension, heat capacity, and viscosity, the key parameters of process chemistry. Its refractive indices in function temperature were also determined. Hereafter, effect (Pd source, nature base, water content mixture, leaving group (−I, −Br, −Cl, −OTf aromatic substrates) on investigated using iodobenzene styrene model substrates. Subsequently, 4‐substituted derivatives applied to investigate electronic efficiency functional tolerance. To demonstrate applicability system, thirteen stilbene isolated with good yields purity (>95 %) 0.2 mol % Pd, 1.5 eq. Et 3 N 1 mL Cyrene 2 h 100 °C.

Nicotinic Acid Derivatives As Novel Noncompetitive α-Amylase and α-Glucosidase Inhibitors for Type 2 Diabetes Treatment

ACS Medicinal Chemistry Letters, Journal Year: 2024, Volume and Issue: 15(9), P. 1474 - 1481

Published: Aug. 5, 2024

A library of novel nicotinic acid derivatives, focusing on the modification position 6 pyridine ring with (thio)ether functionalities, was mostly produced through an innovative green synthetic approach (Cyrene-based) and evaluated for their α-amylase α-glucosidase inhibitory activity. Compounds
