  Many 2-oxoalkyl arenesulfonate derivatives having straight or branched alkyl chains of different lengths, 2-oxoalkyl bis-arenesulfonate derivatives, and alkyl arenesulfonate derivatives having a ketal moiety at the 2-position on the alkyl chain were synthesized, and their esterase-inhibitory activities, as well as hypolipidemic activities, were evaluated.Among these compounds, 1-(2, 4, 6-trimethylbenzenesulfonyloxy)-2-dodecanone (III-1u), and 1-(2, 3, 4, 6-tetramethylbenzenesulfonyloxy)-2-hexanone (III-1w), -2-octanone (III-1x) and -2-decanone (III-1y) exhibited potent esterase-inhibitory activities (IC50=3×10-10, 2×10-10, 2×10<-10> and 3×<-11>M, respectively). However, the sulfonate (XV) having a ketal moiety on the alkyl chain and the bis-sulfonate (XVI) exhibited low inhibitory activities toward esterase in comparison with III and XII. Most of the compounds III and some of the compounds XII exhibited potent hypolipidemic activities corresponding to more than 50% lipid-lowering effect (plasma triglyceride and cholesterol ester) in vivo. The structure-activity relatioinships of these compounds are discussed.

  合成了许多具有直链或支链不同长度烷基链的2-氧代烷基芳磺酸盐衍生物、2-氧代烷基双芳磺酸盐衍生物以及在烷基链的2-位具有缩酮部分的烷基芳磺酸盐衍生物，并评估了它们的酯酶抑制活性及降血脂活性。在这些化合物中，1-(2,4,6-三甲基苯磺酰氧基)-2-十二烷酮（III-1u）、1-(2,3,4,6-四甲基苯磺酰氧基)-2-己烷酮（III-1w）、-2-辛烷酮（III-1x）和-2-癸烷酮（III-1y）表现出强效的酯酶抑制活性（IC50分别为3×10-10、2×10-10、2×10-10和3×10-11M）。然而，相对于III和XII，具有烷基链上缩酮部分的磺酸盐（XV）和双磺酸盐（XVI）对酯酶的抑制活性较低。大多数化合物III和部分化合物XII表现出强效的降血脂活性，对应于体内超过50%的脂质降低效果（血浆甘油三酯和胆固醇酯）。讨论了这些化合物的构效关系。

  Various ketones were converted to the corresponding α-tosyloxyketones with mCPBA and p-toluenesulfonic acid in the presence of a catalytic amount of iodobenzene. Moreover, secondary alcohols were directly converted to the corresponding α-tosyloxyketones using mCPBA and catalytic amounts of iodobenzene and potassium bromide, followed by treatment with p-toluenesulfonic acid in a one-pot manner. Poly(4-iodostyrene)

  各种酮转化成相应的α-tosyloxyketones与米CPBA和p在碘苯催化量的存在对甲苯磺酸。此外，使用m CPBA和催化量的碘代苯和溴化钾将仲醇直接转化为相应的α-甲苯磺酰氧基酮，然后以对-甲苯磺酸的一锅法处理。聚（4-碘苯乙烯）也可用作与酮相同的α-甲苯磺酰化反应的可回收催化剂
• Iodoarene-Mediated α-Tosyloxylation of Ketones with MCPBA and p-Toluenesulfonic Acid

  日期：2011.8

  Alkyl aryl ketones and dialkyl ketones could be converted into the corresponding α-tosyloxy ketones by the reaction with MCPBA and p-toluenesulfonic acid monohydrate (PTSA˙H2O) in the presence of a catalytic amount of molecular iodine (I2) in a mixture of acetonitrile and 2,2,2-trifluoroethanol, although the yields were dependent on the ketones (method A). The same conversion of alkyl aryl ketones and dialkyl ketones into the corresponding α-­tosyloxy ketones could be smoothly carried out by the reaction with MCPBA and PTSA˙H2O in the presence of catalytic amounts of ­iodine and tert-butylbenzene in a mixture of acetonitrile and 2,2,2-trifluoroethanol (method B). In those reactions, p-iodotoluene and 4-tert-butyl-1-iodobenzene were formed at first in method A and method B, respectively, and then they were converted into p-[(hydroxy)(tosyloxy)]iodotoluene and 4-tert-butyl-1-[(hydroxy)(tosyloxy)iodo]benzene by the reaction with MCPBA and PTSA˙H2O. p-[(Hydroxy)(tosyloxy)]iodotoluene and 4-tert-butyl-1-[(hydroxy)-(tosyloxy)iodo]benzene worked as an α-tosyloxylation reagent of ketones.

  烷基芳基酮和二烷基酮可以通过与间氯过氧苯甲酸（MCPBA）和单水合对甲苯磺酸（PTSA·H2O）在催化量的碘分子（I2）存在下反应，在乙腈和2,2,2-三氟乙醇的混合物中，转化为相应的α-甲苯磺酰氧基酮，尽管产率取决于酮类（方法A）。烷基芳基酮和二烷基酮同样可以通过与MCPBA和PTSA·H2O在催化量的碘和叔丁基苯存在下反应，在乙腈和2,2,2-三氟乙醇的混合物中，顺利转化为相应的α-甲苯磺酰氧基酮（方法B）。在这些反应中，方法A和方法B分别首先形成对碘甲苯和4-叔丁基-1-碘苯，然后它们通过与MCPBA和PTSA·H2O反应转化为对[(羟基)(甲苯磺酰氧基)]碘甲苯和4-叔丁基-1-[(羟基)(甲苯磺酰氧基)碘]苯。对[(羟基)(甲苯磺酰氧基)]碘甲苯和4-叔丁基-1-[(羟基)(甲苯磺酰氧基)碘]苯作为酮的α-甲苯磺酰氧化试剂。
• 4-MeC6H4I-Mediated Efficient α-Tosyloxylation of Ketones with Oxone® and p-Toluenesulfonic Acid in Acetonitrile

  日期：2009.12

  Various alkyl aryl ketones, dialkyl ketones, and cycloheptanone were efficiently converted into the corresponding α-tosyl­oxy ketones in good yields by using Oxone® and p-toluenesulfonic acid monohydrate in the presence of p-iodotoluene in acetonitrile. 4-Methoxyacetophenone and 2-acetylthiophene bearing an electron-rich aromatic group could be also converted into the corresponding α-tosyloxyketones smoothly in good yields with the present method. Here, p-iodotoluene works as catalyst and p-[(hydroxy)(tosyloxy)]iodotoluene is formed in situ as a reactive species for the α-tosyloxylation of ketones. However, one equivalent of p-iodotoluene was required to obtain α-tosyloxyketones in good yields and was recovered in 80-20% yields, depending on the reaction conditions.

  通过在乙腈中使用Oxone®和p-甲苯磺酸一水合物，并在p-碘甲苯的存在下，各种烷基芳香酮、二烷基酮和环庚酮高效地转化为相应的α-甲苯磺酰氧基酮，产率良好。带有富电子芳香基团的4-甲氧基苯乙酮和2-乙酰基噻吩也可以用当前方法顺利地转化为相应的α-甲苯磺酰氧基酮，产率良好。在这里，p-碘甲苯作为催化剂，并且原位生成p-[(羟基)(甲苯磺酰氧基)]碘甲苯作为酮的α-甲苯磺酰氧化反应的活性物质。然而，为了获得良好的α-甲苯磺酰氧基酮产率，需要等量的p-碘甲苯，并且根据反应条件的不同，其回收率为80-20%。
