  2‐Hydrazono‐2,3‐dihydro‐1,3-噻唑类化合物意外环扩大为1,3,4‐噻二嗪类化合物

  摘要：

  硫代氨基脲与α-溴乙酰苯的环化可导致形成1,3,4-噻二嗪异构体和两种不同的噻唑。我们研究了使用4-甲基和4-乙基硫代氨基脲作为双亲核基石。在这种情况下，我们观察到了前所未有的2-肼基-2-2,3-二氢噻唑重排为1,3,4-噻二嗪的过程。1,3,4-噻二嗪对噻唑的环收缩很常见，而环的扩张则是新的。反应过程取决于底物的取代方式。

  5-phenyl substituted thiosemicarbazones (MT1–MT11) with the phenyl ring substitutions were prepared and investigated for their inhibitory activities against monoamine oxidases (MAOs) and acetylcholinesterase (AChE). [4-(dimethylamino) phenyl]methylidene}-N-methylhydrazine-1-carbothioamide (MT5) inhibited MAO-B potently with an IC50 of 8.77 µM. Potencies for MAO-B increased in the order N(CH3)2 in MT5 >

• Cyclocondensations of Substituted Thiosemicarbazides with 2-Bromo- 1,2-diphenylethan-1-one

  The cyclocondensation of 4-methylthiosemicarbazide with 2-bromo-1,2-diphenylethan-1-one in ethanol afforded isomeric 2-methylamino-5,6-diphenyl-6H-3,4-thiadiazine and 2-hydrazono-3- methyl-4,5-diphenyl-2,3-dihydro-1,3-thiazole. A pyrazole was obtained by cyclocondensation and subsequent desulfurization of the thiadiazine when the reaction was carried out in concentrated hydrochloric acid. A chemical proof of the structures has been provided. The product distribution of the cyclizations strongly depends on the substitution pattern of the starting materials, and the cyclizations of methylthiosemicarbazide with 2-bromo-1,2-diphenylethan-1-one behaved considerably different from that of the analogous reactions of α-bromoacetophenone.

  在乙醇中，4-甲基硫代氨基脲与 2-溴-1,2-二苯基乙-1-酮发生环缩合反应，得到异构的 2-甲基氨基-5,6-二苯基-6H-3,4-噻二嗪和 2-酰肼基-3-甲基-4,5-二苯基-2,3-二氢-1,3-噻唑。当反应在浓盐酸中进行时，噻二嗪通过环缩合和随后的脱硫反应得到了吡唑。已提供了这些结构的化学证明。环化反应的产物分布在很大程度上取决于起始原料的取代模式，甲基硫代氨基甲酰与 2-溴-1,2-二苯基乙烷-1-酮的环化反应与 α-溴苯乙酮的类似反应有很大不同。

  Complexes [RuCl(H4NO(2)Fo4M)(bipy)(dppb)]PF6 (1), [RuCl(H4NO(2)Fo4M)(Mebipy)(dppb)]PF6 (2), [RuCl(H4NO(2)Fo4M)(phen)(dppb)]PF6 (3), [RuCl(H4NO(2)Ac4M)(bipy)(dppb)]PF6 (4), [RuCl(H4NO(2)Ac4M)(Mebipy)(dppb)]PF6 (5) and [RuCl(H4NO(2)Ac4M)(phen)(dppb)]PF6 (6) with N-4-methyl-4-nitrobenzalde hyde thiosemicarbazone (H4NO(2)Fo4M) and N-4-methyl-4-nitroacetophenone thiosemicarbazone (H4NO(2) Ac4M) were obtained from [RuCl2(bipy)(dppb)], [RuCl2(Mebipy)(dppb)], and [RuCl2(phen)(dppb)], (dppb = 1,4-bis(diphenylphospine)butane; bipy = 2,2'-bipyridine: Mebipy = 4,4'-dimethyl-2,2'-bipyridine: phen = 1,10-phenanthroline). In all cases the thiosemicarbazone is attached to the metal center through the sulfur atom.Complexes (1-6), together with the corresponding ligands and the Ru precursors were evaluated for their ability to in vitro suppress the growth of Trypanosoma cruzi. All complexes were more active than their corresponding ligands and precursors. Complexes (1-3) and (5) revealed to be the most active among all studied compounds with ID50 = 0.6-0.8 mu M.In all cases the association of the thiosemicarbazone with ruthenium, dppb and bipyridine or phenanthroline in one same complex proved to be an excellent strategy for activity improvement.
