37928-17-9, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In a patent, 37928-17-9, molecular formula is C16H13NO, introducing its new discovery.
A method for preparing handkerchief auspicious past cloth sodium (by machine translation)
The invention belongs to the field of medicine and chemical industry, in particular relates to a method for preparing handkerchief auspicious past cloth sodium, aldoximes the benzoate (compound I) with 1-phenyl-1-propyne (compound II), the presence of the catalyst and the acid-binding agent, undergo the addition reaction to construct a isoxazolo, handkerchief auspicious past cloth sodium intermediates obtained (compound III); compound III generating sulfonated, sulfonylation reaction to obtain compound IV, compound IV with propionic anhydride reaction impenetrate handkerchief auspicious past cloth sodium salt obtained (compound V). Innovative of this invention in the preparation of the compound III dipolar cycloaddition reaction, the use of safe low toxicity, relatively stable nature of the common reagent chlorosulfonic acid and ammonia for sulfonylation reaction, with mild reaction conditions, operation is reasonable, high selectivity, product quality and the like; the reaction product used in the low price, the production cost is reduced.
