• Iodoarene-Mediated α-Tosyloxylation of Ketones with MCPBA and p-Toluenesulfonic Acid
  作者：Hideo Togo、Ayumi Tanaka、Katsuhiko Moriyama

  DOI：10.1055/s-0030-1260948

  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

  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%。

  room-temperature ionic liquid (RTIL) supported [hydroxy(tosyloxy)iodo]benzene (ion-supported HTIB) reagent was synthesised by three kinds of effective methods in high yields, which combined the advantages of ionic liquids and the hypervalent iodine. Ion-supported HTIB was an effective reagent for one-step conversion of ketones to the corresponding α-tosyloxylated ketones in the ionic liquid [emim]BF4or acetonitrile

  Regioselective condensation of α‐tosyloxyacetophenones 1 and N‐substituted thioureas 2 in acidic medium to give regioisomers 2‐aminothiazoles I and 2‐imino‐2,3‐dihydrothiazoles II is largely influenced by the substituents present on 1 and 2. A mechanism, supported by DFT calculations has been proposed to explain the observed regioselectively.
