Application In Synthesis of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole<\/a>. The article was titled \u300aA versatile catalyst system for enantioselective synthesis of 2-substituted 1,4-benzodioxanes\u300b. The information in the text is summarized as follows:<\/p>\n

The synthesis of enantiomerically enriched 1,4-benzodioxanes containing alkyl, aryl, heteroaryl and\/or carbonyl substituents at the 2-position was reported. The starting 1,4-benzodioxines were readily synthesized via ring closing metathesis using an efficient nitro-Grela catalyst at ppm levels. Excellent enantioselectivities of up to 99:1 er were obtained by using the versatile catalyst system [Ir(cod)Cl]2\/BIDIME-dimer in the asym. hydrogenation of 2-substituted 1,4-benzodioxines. Furthermore, DFT calculations revealed that the selectivity of the process was controlled by the protonation step; and coordinating groups on the substrate may alter the interaction with the catalyst, resulting in a change in the facial selectivity. In the experiment, the researchers used many compounds, for example, 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0Application In Synthesis of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole<\/a>)<\/p>\n

1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0) belongs to pyrazoles. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, antidiabetic and antibacterial activities.
