  • Enantioselective total synthesis of pyrroloquinolone as a potent PDE5 inhibitor
    作者:Nagula Shankaraiah、Leonardo Silva Santos
    DOI:10.1016/j.tetlet.2008.09.151
    日期:2009.2
    A concise enantioselective strategy for the synthesis of key PDE5 inhibitor 2 was developed in 5 and 6 steps using asymmetric hydrogenation and one-pot chiral auxiliary approaches, respectively. The synthesis features the use of imine 6 obtained through Bischler–Napieralsky reaction from amide 5. Absolute R configuration was introduced in (+)-7 by asymmetric transfer-hydrogenation reaction with Ru(II)
    分别使用不对称氢化和一锅手性辅助方法,分5个步骤和6个步骤开发了用于合成关键PDE5抑制剂2的简洁对映选择性策略。合成的特征是使用通过Bischler-Napieralsky反应从酰胺5中获得的亚胺6。通过与Ru(II)催化剂的不对称转移加氢反应,在(+)- 7中引入绝对R构型,然后使用Winterfeldt氧化方法建立三环吡咯并喹诺酮核。在亚胺6分子中引入手性的另一种替代合成方法和不同手性助剂的氯甲酸酯,获得了N-酰亚胺离子中间体,这些中间体使用PdCl 2 / Et 3 SiH方案原位还原。这些合成途径被应用于有希望的男性勃起功能障碍(MED)PDE5抑制剂1的总合成中。
  • Palladium asymmetric reduction of β-carboline imines mediated by chiral auxiliaries assisted by microwave irradiation

    日期:2009.12
    An alternative synthetic approach for the introduction of chirality in β-carboline moiety through in situ reduction of N-acyliminium ion intermediates generated from imine 2 and chloroformate of 8-phenylmenthyl as chiral auxiliary was achieved. The method applied microwave-assisted irradiation and used PdCl2/Et3SiH protocol as a mild reducing agent, which decreased reaction times to minutes when compared
    通过原位还原由亚胺2和8-苯基薄荷基的氯甲酸酯作为手性助剂生成的N-酰基亚胺离子中间体,实现了另一种在β-咔啉部分中引入手性的合成方法。该方法采用微波辅助辐射,并使用PdCl 2 / Et 3 SiH协议作为温和的还原剂,与常规的热反应相比,该方法将反应时间缩短至数分钟。还原产生的R-胺的非对映选择性(4-12:1),与从Noyori不对称氢化催化剂获得的产物相比,在手性辅助去除和光谱数据后将其分配。
  • Enantioselective Imine Reduction of Dihydro-β-carbolines by Fe-Thiosquaramide Catalyst

    Enantioselective imine reduction of dihydro-β-carbolines (DHBCs) is a reliable and powerful tool to construct bioactive chiral tetrahydro-β-carbolines (THBCs). Here, we report an efficient enantioselective imine reduction employing in situ generated Fe-thiosquaramides (Fe-TSQs) 3a and 3b as asymmetric organometallic catalysts to produce chiral THBCs (2a–h). The catalyst 3a at 15 mol % was found to
    二氢-β-咔啉 (DHBC) 的对映选择性亚胺还原是构建具有生物活性的手性四氢-β-咔啉 (THBC) 的可靠且强大的工具。在这里,我们报告了一种有效的对映选择性亚胺还原,采用原位生成的 Fe-thiosquaramides (Fe-TSQs) 3a和3b作为不对称有机金属催化剂来生产手性 THBC ( 2a – h )。发现 15 mol%的催化剂3a适用于具有烷基和芳基的底物,这些底物提供具有优异对映选择性(高达 ee 99%)的相应手性 THBC。

  • Stereoselective bioreduction of β-carboline imines through cell-free extracts from earthworms (Eisenia foetida)
    作者:Yaneris Mirabal-Gallardo、Maria del Pilar C. Soriano、Leonardo S. Santos
    DOI:10.1016/j.tetasy.2013.03.003
    日期:2013.4
    Although remarkable advances have been made over the last decade in organic synthesis, catalysis, and biotechnology, there is still a need to introduce and develop new processes for chemical production to achieve sustainable and cleaner approaches to support the increasing global pharmaceutical/chemical industry. There is a growing need to produce optically active compounds in high yields to maintain and support areas such as pharmaceutical and natural product synthesis. Thus, chemists today are looking for alternative reactions carried out under green conditions. In this context, we describe beta-carboline imine reductions employing cell-free extracts from red Californian earthworms (Eisenia foetida) in high yields and enantiomeric excesses. The enantiomeric excess values of the bioreduction showed no dependence on the imine 1a-g substituents to afford amines with an (R)-configuration. Based on these data, a model for the cell-free extract from the earthworm is proposed. (C) 2013 Elsevier Ltd. All rights reserved.
