In an article, author is Liu, ZP, once mentioned the application of 611-14-3, Name is 1-Ethyl-2-methylbenzene, molecular formula is C9H12, molecular weight is 120.1916, MDL number is MFCD00009257, category is isothiazole. Now introduce a scientific discovery about this category, SDS of cas: 611-14-3.
A novel synthetic approach to benzo[d]isothiazole 1,1-diones having a secondary alkyl substituent at the 3-position
A novel method for the synthesis of benzo[d]isothiazole 1,1-diones with a secondary alkyl substituent at the 3-position is described. Treatment of N-tert-butylbenzenesulfonamide (1) with an excess of BuLi, followed by the reaction with methyl 2-arylpropanoate, gave the corresponding ortho-functionalized benzenesulfonamides 2a-d, which underwent cyclization under TMSCl-NaI-MeCN reflux conditions to afford 3-substituted benzo[d]isothiazole 1,1-diones 3a-d.
