  4,5-Dialkylsubstituted 2-imino-1,3-thiazolidine derivatives as potent inducible nitric oxide synthase inhibitors

  摘要：

  In the course of our search for selective iNOS inhibitors, we have previously reported that 2-imino-1,3-oxazolidine derivatives (1) and 2-aminothiazole derivatives (2) are selective iNOS inhibitors. In order to find more potent iNOS inhibitors, we focused our efforts on the synthesis and evaluation of the inhibitory activity against iNOS and selectivity for iNOS both in vitro and in vivo of a series of 2-imino-1,3-thiazolidine derivatives (3), which are analogues of I and 2. Our results show that among the compounds synthesized (4R,5R)-5-ethyl-2-imino-4-methyl-1,3-thiazolidine [(4R,5R)-14a: ES-1537] exhibited potent inhibitory activity and selectivity for iNOS. In addition, ES-1537 had good pharmacokinetic profile in rats with BA value of 80%. It is therefore expected that ES-1537 may be therapeutically useful for the treatment of diseases related to excess production of NO. (C) 2004 Elsevier Ltd. All rights reserved.

  对映体纯β-氨基醇的合成。二乙基锌螯合控制加成至α-（二苄氨基）醛的简单例子。

  摘要：

  对映体纯的顺式-2-氨基醇6是通过将二乙基锌加到手性α-（二苄基氨基）醛4上而制备的。该加成物具有高度的立体选择性，从而制得具有出色的非对映异构体过量的顺式2-（二苄基氨基）醇5（76-98 ％）。通过在Pearlman催化剂上进行氢解将5脱苄基化，可定量得到氨基醇6。

  Enantiomerically pure anti-β-amino alcohols were synthesized from optically pure α-(N,N-dibenzylamino)benzyl esters, derived from α-amino acids, by the sequential reduction to aldehyde with DIBAL-H at −78 °C and subsequent in situ addition of Grignard reagents. Besides anti-β-amino alcohols, anti-2-amino-1,3-diols and anti-3-amino-1,4-diols were obtained in good yields (60–95%) and excellent stereoselectivity

  对映体纯的抗-β-氨基醇是由衍生自α-氨基酸的光学纯的α-（N，N-二苄基氨基）苄基酯合成的，方法是在-78°C下依次用DIBAL-H还原为醛，然后在原位添加格氏试剂。除了抗-β-氨基醇，抗2 -氨基- 1,3-二醇和抗以良好的收率（60-95％）和优异的立体选择性获得-3-氨基-1,4-二醇的（de> 95％ ）。我们的技术与底物中存在的游离羟基相容。为了证明该方法的多功能性，从适当的步骤分两步合成了spisulosine和sphinganineN，N-二苄基-1-氨基苄基酯的产率分别为42％和45％。
• Unprecedented rearrangement reaction of 2-aziridinemethanols with “lower order” lithium methylcyanocuprate

  Complementary selectivity can be achieved in ring opening reactions of 2-aziridinemethanols by using either the Gilman reagent or lower order cyanocuprate. In the former case, the usual attack of the Gilman reagent to the substrates 1 and 2 results in the formation of the expected ring opening products (3 and 4) and (7 and 8), respectively. In contrast, exposure of both 1 and 2 to the lower order cyanocuprate

  可以通过使用吉尔曼试剂或低级氰尿酸酯在2-氮丙啶甲醇的开环反应中实现互补的选择性。在前一种情况下，吉尔曼试剂对底物1和2的通常攻击导致分别形成了预期的开环产物（3和4）和（7和8）。相反，将1和2都暴露于低级氰铜酸盐中却以前所未有的方式进行，大概是通过环氧化物D和G来生成意想不到的仲醇（11和12）作为主要产品。

  In our search for a novel class of inducible nitric oxide synthase (NOS) inhibitors, 1,3-oxazolidin-2-imine was found to weakly inhibit iNOS. Further modifications of this compound resulted in a remarkable increase in both the in vivo and in vitro inhibitory activity and selectivity for iNOS. (C) 2003 Elsevier Ltd. All rights reserved.
• Aza-Payne Rearrangement of Activated 2-Aziridinemethanols and 2,3-Epoxy Amines under Basic Conditions

  An aza-Payne rearrangement of activated 2-aziridinemethanols with t-BuOK, NaH, or KH at near 0 degrees C in common solvents such as THF, toluene, 1,2-dimethoxyethane, 1,4-dioxane, or a mixed solvent of THF-HMPA followed by quenching at -78 degrees C gives the corresponding epoxysulfonamides. Exposure of N-tosyl-(2S)-azetidinemethanol (36) and N-tosyl-(S)-prolinol (37) to NaH or KH in dichloromethane yielded only the respective dimeric compounds that resulted by joining 2 equiv of reactant through a methylene group. Reaction of N-tosyl-(2S,3S)-3-methyl-2-aziridinemethanol (9) and its (2R,3S)-isomer 23 with Gilman reagents (R(2)CuLi; R = Me and Bu) or ''higher order'' cuprates [R(2)Cu(CN)Li-2; R = Me and Bu] yielded the two expected aziridine ring-opening products. In sharp contrast, treatment of 9 and 23 with ''lower order'' cuprates afforded rearrangement-opened products. Thus, if the nucleophile is highly reactive, then the expected nucleophilic ring opening of the aziridine predominates. However, if the nucleophile is less reactive, then it becomes possible to cleave the resulting rearranged epoxide. Upon exposure of 2,3-epoxy amines to an equimolar mixture of t-BuOK-n-BuLi in a mixed solvent of THF and n-hexane at -78 degrees C, the equilibrium lies exclusively toward the hydroxy aziridine forming direction.
