A decarbonylation free, polystyrene-supported, Pd (Pd@PS)-catalysed carbonylative esterification of the hydroxy group of 5-hydroxymethyl furfural (5-HMF) to its corresponding aryl esters has been developed. The use of Pd@PS, oxalic acid as CO source, and aryl halides was first explored for the aryl ester of 5-HMF synthesis. Here, we investigated the vital role of a polystyrene support to avoid the commonly known decarbonylation of 5-HMF. The reaction exhibits vast substrate scope with comparably good yield and catalyst recyclability.

3-Substituted indolin-2-one derivatives had been designed and synthesized as a novel class ofprotein tyrosine phosphatase 1B (PTP1B) inhibitors. These compounds had been evaluated for their inhibitory activities against PTP1B in vitro with IC50 values in a low micromolar range.Compound 36, the lowest, bore an IC50 value of 3.48 μM. Preliminary structure-activity relationship was summarized.
