One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C10H7NO2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 486-73-7, Name is Isoquinoline-1-carboxylic acid, molecular formula is C10H7NO2
C-10 ester and ether derivatives of dihydroartemisinin – 10-alpha artesunate, preparation of authentic 10-beta artesunate, and of other ester and ether derivatives bearing potential aromatic intercalating groups at C-10
Preparative and stereochemical aspects of reactions providing new C-10 ester and ether derivatives of the antimalarial drug dihydroartemisinin (DHA, 2) have been examined. beta-Artesunate has been prepared for the first time, and has been differentiated from the antimalarial alpha-artesunate; the latter has been incorrectly designated as the beta-epimer in Chemical Abstracts and some primary literature. New ester and ether derivatives bearing potential intercalating groups have been synthesised by means of the Schmidt, Mitsunobu and DCC coupling procedures, by acylation in the presence of DMAP, or by hydroxy activation with BF3 as catalyst. When the hydroxy group of DHA acts as a nucleophile towards activated carboxy groups in acylating agents or the DCC intermediate, alpha-esters are obtained exclusively. When the hydroxy group is activated for displacement by nucleophiles, as in the Schmidt or Mitsunobu procedures, beta-esters and beta-ethers are obtained either exclusively or predominantly. An exception is represented by the Mitsunobu procedure involving DHA and 1- and 2-naphthols, in which mixtures of epimers are obtained; however, exclusive formation of beta-aryl ethers takes place when the Schmidt procedure is used, with activation of the intermediate trichloracetimidate by SnCl2. The latter method is therefore superior to patented procedures for the preparation of beta-aryl ethers from nonbasic aryl alcohols without detectable rearrangement to C-aryl compounds. However, the Mitsunobu procedure is better when basic aromatic alcohols are used as nucleophiles. The formation of alpha-products in which the hydroxy group of DHA acts as a nucleophile is of biological significance in relation to enzyme-mediated Phase II glucuronidation of DHA, in which only the alpha-DHA glucuronide is formed.
