Mosallanejad, Arash;Lorthioir, Olivier research published \u300a Application of Tsunoda reagent to the convenient synthesis of drug-like pyrazoles\u300b, the research content is summarized as follows. The versatility of the under-utilized (cyanomethylene)tributylphosphorane (CMBP, Tsunoda reagent) was demonstrated on two occasions in a drug discovery context. Firstly, the high reactivity of the phosphorane allowed the alkylation of a weakly acidic pyrazole when standard Mitsunobu conditions were unsuccessful. Secondly, the clean reaction profile generally obtained using CMBP allowed the direct use of the crude mixture in a subsequent Suzuki cross coupling. This reagent was utilized when isolation of the Mitsunobu reaction product (e.g. containing a boronate) was not desirable.<\/p>\n

269410-08-4, 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, also known as 4-Pyrazoleboronic acid pinacol ester , is a useful research compound. Its molecular formula is C9H15BN2O2 and its molecular weight is 194.04 g\/mol. The purity is usually 95%.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is a useful reagent for Suzuki-Miyaura cross-couplings as well as Ruthenium-catalyzed asymmetric hydrogenation. 4-Pyrazoleboronic acid pinacol ester is also a useful reagent for preparing VEGF, Aurora, RHO (ROCK), Janus Kinase 2, c-MET, ALK, S-nitrsoflutathione reductase, CDC7, Acetyl-CoA carboxylase inhibitors.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is used in the preparation of Rho kinase (ROCK) inhibitors as wella s other biologically active compounds.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is an organic compound that is the product of a bifunctional coupling reaction between 4-pyrazolecarboxylic acid and pinacol. It has been shown to inhibit protein S6 kinase, which is involved in the regulation of cell growth and proliferation. This compound has also been shown to be effective against cancer cells, including those that are resistant to conventional chemotherapeutic drugs. 4-Pyrazoleboronic acid pinacol ester may also be used as a precursor for other compounds with pharmaceutical activity., HPLC of Formula: 269410-08-4<\/a><\/p>\n
