Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is El-Hashash, Maher A., once mentioned the application of 108-26-9, Name is 3-Methyl-1H-pyrazol-5(4H)-one, molecular formula is C4H6N2O, molecular weight is 98.1, MDL number is MFCD00020699, category is piperidines. Now introduce a scientific discovery about this category, Recommanded Product: 108-26-9.
Ultrasonic Aptitude of Regioselective Reaction of 6-bromo-spiro-3,1-benzoxazinone2,1-isobenzofuran-3,4-dione Towards Some Electrophilic and Nucleophilic Reagents
In the present work, the 2-benzoxazinonyl benzoic acid (BBA) could be isomerized to the stereogenic spiro products (SBI) via ultrasonic and basic reaction conditions. The spiro compounds (SBI) have both electrophilic and nucleophilic centers. A series of nitrogen nucleophiles such as hydrazine hydrate, glycine, 2-aminopyridine, 2-picolinylamine, 4-anisidine, 4-aminoacetophenone and carbon electrophiles such as oxiranylmethylchloride, ethylchloroacetate, chloroacetylchloride, Mannich reagents, for example, formaldehyde with piperidine or morpholine can be treated with 2-benzoxazine-2-yl benzoic acid (BBA) via multicomponent reaction. The basicity of previous nucleophiles can be controlled on the course of reaction of 2-benzoxazinonyl benzoic acid. The chemical structure of the synthesized compounds can be confirmed by microanalytical, spectral data and optimized by quantum chemical parameters.
