  1-aryl-2-烷基-1,2-二酮与 2-aroyl-1-chlorocyclopropanecarboxylates 的底物依赖性反应：选择性获得 2',5'-dicyclopropoxy-1,1':4',1'' -四芳基和五富烯

  摘要：

  一种有趣的底物控制一锅法，用于高度取代的 2',5'-dicyclopropoxy-1,1':4',1''-teraryls 和 6-hydroxypentafulvenes，涉及各种 1,2-二酮和 2-aroyl-1作为由Cs 2 CO 3触发的3C Michael受体的-氯环丙烷羧酸盐已经被开发出来。我们注意到 1,2-二酮在该反应中起决定性作用以确定产物的选择性。例如，在1,2-二酮的对位和间位具有贫电子官能团的芳环通过具有高应变环丙烯的环二聚/双氧杂迈克尔过程选择性地产生 2,5-二芳基对苯二酚。然而，当 1-萘基/给电子芳基/邻选择-芳基取代的 1,2-二酮，迈克尔引发的扩环反应（C-C 和 C C 键）在相同的条件下发生，主要产生相应的五富烯。此外，该反应具有良好的非对映选择性、广泛的底物范围、良好的官能团耐受性、无过渡金属工艺等几个重要特征。

  Various ketones were smoothly converted into the corresponding α-tosyloxyketones with MCPBA and p-toluenesulfonic acid in the presence of a catalytic amount of ionic-liquid (IL)-supported PhI in room temperature ionic liquid, [emim]OTs. Moreover, the present ionic-liquid reaction media containing a catalytic amount of IL-supported PhI could be reused for the same α-tosyl­oxylation of ketones and thiazoles directly, keeping good yields.

  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。

  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%。

  α-iodoketone and a subsequently formed α-iodosylketone. The latter reacts with the sulfonic acid to afford the α-sulfonyloxyketone product. Alkyl aryl ketones are converted into the corresponding α-sulfonyloxyketones, in moderate to excellent yields, via a novel procedure that utilizes Oxone®, p-toluenesulfonic acid or methanesulfonic acid and molecular iodine in a mixture of acetonitrile and 2,2,2-trifluoroethanol

  alpha-Tosyloxyketones and alpha-tosyloxyaldehydes were directly prepared from alcohols by treatment with iodosylbenzene and p-toluenesulfonic acid monohydrate in good yields. This method can be used for the direct preparation of thiazoles, imidazoles, and imidazo[1,2-alpha]pyridines from alcohols in good to moderate yields by the successive treatment with iodosylbenzene and p-toluenesulfonic acid monohydrate, followed by thioamides, benzamidine, and 2-aminopyridine, respectively.
