  描述：

  [2-Methyl-3-(2-methyl-propane-1-sulfonyl)-5-nitro-phenylsulfanyl]-acetic acid methyl ester 在 哌啶 、 双氧水 作用下， 以 溶剂黄146 、 苯 为溶剂， 反应 1.0h， 生成 3-(4-Fluoro-phenyl)-5-(2-methyl-propane-1-sulfonyl)-7-nitro-1,1-dioxo-1λ⁶-thiochroman-2-carboxylic acid methyl ester

  摘要：

  Treatment of 2,4,6-trinitrotoluene with beta-mercaptocarboxylic acid esters and subsequent oxidation gave 2-(alkoxycarbonyl-R-methylsulfonyl)-4-X-6-nitrotoluenes which were brought into Knoevenagel condensation with aromatic aldehydes (heating in benzene in the presence of secondary amine acetates). As a result of intramolecular cyclization, 2-alkoxycarbonyl-3-aryl-2-R-5-X-7-nitrothiochroman 1,1-dioxides (R = H, Me; X = NO2, R'SO2) were obtained. The developed procedure opens the way to hitherto unknown thiochroman 1,1-dioxide derivatives.
