  N-Acylhydrazones as inhibitors of PDE10A

  摘要：

  Cyclic nucleotide phosphodiesterases (PDEs) are represented by a large superfamily of enzymes. A series of hydrazone-based inhibitors was synthesized and shown to be novel, potent, and selective against PDE10A. Optimized compounds of this class were efficacious in animal models of schizophrenia and may be useful for the treatment of this disease. (C) 2011 Elsevier Ltd. All rights reserved.

  Thiolate ions add regiospecifically to N-(4-oxopyridin-1-yl)pyridinium salts (2)–(7) to give in good to excellent yields only the 1,4-dihydropyridine adducts (8)–(13), regardless of whether or not the pyridone moiety carries substituents for sterically shielding the 2- and 6-positions of the pyridinium ring. The addition is believed to be thermodynamically controlled. Decomposition of the dihydro-adducts

  (AD-HoC) with nickel under visible-light-driven redox reaction conditions for general C(sp2)–(hetero)atom coupling reactions. The self-adjustive nature of the catalytic system allowed the simple classification of dozens of various classes of nucleophiles in cross-coupling reactions. This is synthetically demonstrated in nine different bond-forming reactions (in this case, C(sp2)–S, Se, N, P, B, O, C(sp3, sp2

  交叉偶联反应是现代有机合成中最重要的转化之一1,2,3。尽管考虑到各种方案，报道的（杂）芳基卤化物和亲核试剂偶联配偶体的范围非常大，但化合物类别之间的反应条件差异很大，因此需要根据具体情况重新优化反应条件4。在这里，我们介绍了在可见光驱动的氧化还原反应条件下镍的自适应动态均相催化（AD-HoC），用于一般的 C( sp 2 )–(杂)原子偶联反应。催化系统的自我调节性质允许在交叉偶联反应中对数十种不同类别的亲核试剂进行简单分类。这在九种不同的成键反应（在本例中为 C( sp 2 )–S、Se、N、P、B、O、C( sp 3、  sp 2、  sp )、Si、Cl）中得到了综合证明在可预测的反应条件下进行数百个合成实例。催化反应中心和条件因添加的亲核试剂或如果需要而添加市售的廉价胺碱而彼此不同。

  日期：1999.6

  Hydrazides were treated with ceric(IV) ammonium nitrate (CAN) in the presence of the appropriate alcohol as a nucleophile to afford esters in good yields. Reactions took place exclusively at the hydrazino moiety even when other sensitive groups were present in either of the partners. (C) 1999 Elsevier Science Ltd, All rights reserved.
