On May 31, 2007, Ren, Sumei; Mcnamara, Paul; Koharski, David; Hesk, David; Borges, Scott published an article.Computed Properties of 220851-46-7 The title of the article was Synthesis of sulfur-35 reagents for protein labeling. And the article contained the following:

Two 35S reagents were developed to radiolabel proteins. The first reagent, Me35SO2NHCH2C6H4CO2H-p N-hydroxysuccinimide (NHS) ester (SMSB), acylates the ε-amino group of lysine residues in proteins. The second reagent, aldehyde Me35SO2NHCH2C6H4CH2CH2CHO-p (MSAPPA), labels lysine residues via reductive alkylation. Comparing the two methods, the reductive alkylation method labeled proteins over a broader pH range with higher overall radiochem. yield. The biol. activity of the proteins did not change after labeling with these 35S reagents. The experimental process involved the reaction of tert-Butyl 4-((((benzyloxy)carbonyl)amino)methyl)benzoate(cas: 220851-46-7).Computed Properties of 220851-46-7

All the compounds synthesized were confirmed by 1H NMR and ESI-MS. The effects of solvent, temperature, metal ion and some other factors to the reaction were investigated. A possible mechanism for this reaction was proposed. The study provided a new method for this type of synthesis in the future.

On September 26, 2022, Wang, Songlin; Jiang, Nan; Peng, Jiali; Yang, Peng; Cui, Chengxing; Niu, Hongying; Zhang, Qiying; Wang, Jianji published an article.Reference of Phenyl Salicylate The title of the article was Efficient Synthesis of Diphenyl Carbonate from CO2, Phenol, and Carbon Tetrachloride under Mild Conditions. And the article contained the following:

Herein, an efficient catalytic system for the direct synthesis of DPC from CO2, phenol, and carbon tetrachloride was developed by using a ZnCl2/copper triflate (Cu(OTf)2) composite catalyst. For the first time, high yield and high selectivity were achieved for DPC synthesis under mild conditions, even at atm. pressure. Carefully designed control experiments and DFT studies indicated that the synergistic activation of Cu(OTf)2 and its anion complex with ZnCl2 for phenol and CO2 led to a remarkably improved catalytic activity through a Lewis acid-assisted catalysis. This study not only provides a new strategy for efficient preparation of DPC but also offers an effective pathway for better CO2 utilization.

We report decarboxylative carbonyl α-arylation by coupling of arylboron nucleophiles with malonic acid derivatives This process is enabled by the merger of aerobic oxidative Cu catalysis with decarboxylative enolate interception reminiscent of malonyl-CoA reactivity in polyketide biosynthesis. This method enables the synthesis of monoaryl acetate derivatives containing electrophilic functional groups that are incompatible with existing α-arylation reactivity paradigms. The utility of the reaction is demonstrated in drug intermediate synthesis and late-stage functionalization.
