  Regiospecific Functionalization of 1,3-Dihydro-2H-benzimidazol-2-one and Structurally Related Cyclic Urea Derivatives

  摘要：

  Methods for selectively protecting one of the degenerate nitrogen atoms of the cyclic urea derivatives 1,3-dihydro-2H-benzimidazol-2-one (6a), 1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (11), 1,3-dihydro-2H-imidazo[4,5-b]quinolin-2-ones (20), 1,3-dihydro-2H-imidazo[4,5-c]pyridin-2-one (22), and 1,3-dihydro-4-phenyl-2H-imidazol-2-one (27) were developed. Heating these cyclic ureas with ethyl 2-pyridyl carbonate in the presence of a base in CH3CN at reflux or DMF at 100 degrees C cleanly provided the monoethoxycarbonyl derivatives 7a, 12, 21, 23, and 28, respectively. Alternatively, treatment of 6a with an excess of diethyl pyrocarbonate or di-tert-butyl dicarbonate afforded the bis-alkoxycarbonyl derivatives 8a and 8b, respectively, which underwent disproportionation to 7a and 7b upon heating with 1 mol equiv of 6a and K2CO3 in CH3CN at reflux. The regiochemistry of the introduction of alkoxycarbonyl groups to benzimidazol-2-one derivatives was not significantly influenced by an electron-withdrawing (CF3, 6b) or an electron-donating (OCH3, 6c) substituent at C-5 of the heterocyclic ring. However, the reaction was found to be sensitive to steric factors since a chlorine substituent ortho to one of the urea N atoms (6e) completely directed the alkoxycarbonyl moiety to the less sterically encumbered N atom, affording a single product (7f, 7g). Alkylation of 7a-g proceeded efficiently to provide products 10a-10ag after removal of the protecting group. Halogenation of monoprotected benzimidazol-2-one 7a occurred regiospecifically to give the monohalo derivatives 7h, 7i, and 7k, the identity of which were readily established from the characteristic chemical shift and spin coupling pattern in their 1H NMR spectra. A protecting group interchange strategy that took advantage of the distinctive chemical reactivities of the EtO(2)C and t-BuO(2)C protecting groups toward isopropylamine was developed that provided access to the isomerically substituted series of monohalo, mono-N-alkylated benzimidazol-2-ones 71 and 7m. The efficient derivatization of the unprotected N atom of these monoprotected cyclic urea derivatives was accomplished by treating with activated and unactivated halides in the. presence of K2CO3 or exposure to alcohols under Mitsunobu conditions. In several cases, mixtures of O- and N-alkylated products were produced which were readily separated by chromatography. Alkylation of 7h with activated halides, using K2CO3 in CH3CN at reflux, occurred without protecting group equilibration; however, a mixture of isomeric alkylated products was obtained when 7h was heated at 110 degrees C in DMF with cyclohexylmethyl bromide in the presence of K2CO3 as the base. Derivatization of 7h under Mitsunobu reaction conditions proceeded with retention of the topological substituent relationships. Subsequent removal of the alkoxycarbonyl moiety afforded monoalkylated cyclic urea derivatives.

  Due to the complex and multifactorial nature of bipolar disorder (BD), single‐target drugs have traditionally provided limited relief with no disease‐modifying effects. In line with the polypharmacology paradigm, we attempted to overcome these limitations by devising two series of multitarget‐directed ligands endowed with both a partial agonist profile at dopamine receptor D3 (D3R) and inhibitory activity

  由于双相情感障碍（BD）的复杂性和多因素性质，传统上，单靶标药物只能提供有限的缓解作用，而没有改善疾病的作用。根据多药理学范式，我们试图通过设计两个在多巴胺受体D3（D3R）上具有部分激动剂谱和对糖原合酶激酶3β（GSK-3β）的抑制活性的多目标导向配体来克服这些限制。 。这是两个在结构上不相关的目标，它们在认知和情绪调节中发挥独立但相互联系的作用。两种化合物（7和10）成为有前途的D3R /GSK-3β多靶标配体，在D3R具有纳摩尔活性，对GSK-3β具有低微摩尔抑制作用，从而初步证实了我们策略的可行性。此外，有7个在稳定性和药代动力学研究中显示出有希望的类药物特性。
