Abstract A series of 1-(substituted phenyl)-3-[α-(alkyloxyimino)-benzylidene]pyrrolidine-2,4-dione derivatives as a mixture of two geometrical isomers of Z-configuration and E-configuration were synthesized by the reaction of the corresponding α-hydroxybenzylidene analogs with alkyloxyamine hydrochlorides. The target compounds were confirmed by IR, 1H NMR, MS and elemental analysis. The title compounds

Electron-rich ruthenium phthalocyanine complexes were evaluated in carbene transfer reactions from ethyl diazoacetate (EDA) to aromatic and aliphatic olefins as well as to a wide range of aromatic, heterocyclic and aliphatic amines for the first time. It was revealed that the ruthenium octabutoxyphthalocyanine carbonyl complex [(BuO)8Pc]Ru(CO) is the most efficient catalyst converting electron-rich
富电子钌酞菁配合物是首次从重氮乙酸乙酯(EDA)到芳香族和脂肪族烯烃以及各种芳香族,杂环和脂肪族胺的卡宾转移反应中进行评估的。结果表明,八丁氧基酞菁钌羰基络合物[(BuO)8Pc] Ru(CO)是最有效的催化剂,在低催化剂负载和几乎等摩尔的底物条件下,可以将高电子含量和电子贫乏的芳族烯烃转化为环丙烷衍生物,并具有高收率(通常为80–100%)和高TON(最高为1000)。 / EDA比。该催化剂在卡宾插入胺N–H键中显示出罕见的效率。使用0.05摩尔%的催化剂负载量,高胺浓度(1M)和1.1当量。在EDA的作用下,许多结构不同的胺被选择性地转化为单取代的甘氨酸衍生物,其定量收率和周转数均达到2000。高选择性,大底物范围,低催化剂载量和实际反应条件[[BuO)8 Pc ] Ru(CO)是卡宾插入胺中最有效的催化剂。

[PROBLEMS] To provide an agent useful for the prevention or treatment of various diseases associated with the infection with acyclovir-resistant viruses of the family Herpesviridae, specifically various infectious caused by herpesviruses, such as varicella associated with varicella-zoster virus infection, herpes zoster associated with recurrent infection with latent varicella-zoster virus, and herpes labialis, herpes encephalitis and genital herpes associated with HSV-1 and HSV-2 infection, and the like.
[MEANS FOR SOLVING PROBLEMS] An N-[2-[(4-substituted phenyl)amino]-2-oxoethyl]tetrahydro-2H-thiopyran-4-carboxamide derivative in which the phenyl group is substituted at position 4 by a specific 5- or 6-membered heteroaryl group. This derivative has an excellent anti-viral activity against acyclovir-resistant herpesviruses and, therefore, is effective for the treatment of the diseases as mentioned above.
A pharmaceutical drug, particularly a novel compound useful for the prophylaxis or therapeutic treatment of various diseases involving infections with viruses of the Herpesviridae family, specifically various herpesvirus infections such as varicella (chicken pox) via varicella zoster virus, varicella zoster via recurrent infection with latent varicella zoster virus, herpes labialis and herpes encephalitis via HSV-1 and genital herpes via HSV-2 infection. N-2-[(4-Substituted phenyl)amino]-2-oxoethyl}tetrahydro-2H-thiopyran-4-carboxamide derivative where the phenyl group is substituted at position 4 with a specific five-membered or 6-membered heteroaryl group, has such great anti-virus activity that the oral dosing thereof at a low dose enabled the therapeutic treatment of the diseases.

complexes bearing n-OBu substituents in the peripheral or non-peripheral positions are efficient catalysts for the selective double or single carbene insertion to the amine N–H bonds. This complementary reactivity of two Ru complexes can be used for the synthesis of asymmetric tertiary amines and diamines bearing different substituents and has been demonstrated by two examples of readily available primary
