  氧化酰胺化-Bischler-Napieralski反应合成异喹啉生物碱

  摘要：

  已经开发出通过在氧化酰胺化条件下将伯胺与芳基二溴乙酮偶联来直接合成 α-酮酰胺。然后将 α-酮酰胺在 Bischler-Napieralski 条件下进行杂环脱水反应，然后在两阶段过程中用 DBU 芳构化提供 1-苯甲酰基异喹啉。利用这种方法，异喹啉生物碱如沙米克林酮、罂粟碱和普氏碱 A 以极好的收率合成。

  Novel total syntheses of oxoaporphine alkaloids such as liriodenine, dicentrinone, cassameridine, lysicamine, oxoglaucine and O-methylmoschatoline were developed. The key step of these total syntheses is Cu-catalyzed conversion of 1-benzyl-3,4-dihydro-isoquinolines (1-Bn-DHIQs) to 1-benzoyl-isoquinolines (1-Bz-IQs) via tandem oxidation/aromatization. This novel Cu-catalyzed conversion has been studied

  ols as building blocks for divergent syntheses of different types of benzylisoquinoline alkaloids. Photochemical cyclization of ortho-bromo analogues under reductive conditions gives oxoaporphine alkaloids. Nine benzylisoquinoline alkaloids and two oxoaporphine alkaloids were obtained in two or three steps from appropriate isoquinolines.

  甲氧基和苄氧基取代的异喹啉在C-1处用Knochel–Hauser碱进行区域选择性金属化，随后被芳族醛捕获，从而得到芳基（异喹啉-1-基）甲醇作为不同类型的苄基异喹啉生物碱的不同合成的基础。在还原条件下邻溴代类似物的光化学环化反应得到氧磷卟啉生物碱。从适当的异喹啉分两步或三步获得了九种苄基异喹啉生物碱和两种氧磷卟啉生物碱。

  1a resembles that of the cis alkene 1. Additional inactive compounds prepared include the benzylisoquinoline series 28-32 as well as the protoberberines 38 and 39. Shortening the two-carbon bridge of 1a to a one-carbon bridge in the diphenylmethane 20 resulted in a decrease in cytotoxicity and tubulin polymerization inhibitory activity. Although the corresponding benzophenone 18 was as active as 1a as

• Transition metal-free Minisci reaction promoted by NCS, and TBHP: acylation of heteroarenes
  作者：Yogesh Siddaraju、Kandikere Ramaiah Prabhu

  DOI：10.1016/j.tet.2015.12.065

  日期：2016.2

  A method for acylation for heteroarenes under metal-free conditions has been described using NCS as an additive and TBHP as an oxidant. This method has been successfully employed in acylation of a variety of aldehyde with heteroarenes. The application of the method has been illustrated in synthesizing isoquinoline derived natural products. This strategy provides an efficient, mild and inexpensive method for acylation of heteroarenes. (C) 2015 Elsevier Ltd. All rights reserved.

  日期：2014.5.2

  Transition metal-free acylation of isoquinoline, quinoline, and quinoxaline derivatives has been developed employing a cross dehydrogenative coupling (CDC) reaction with aldehydes using substoichiometric amount of TBAB (tetrabutylammonium bromide, 30 mol %) and K2S2O8 as an oxidant. This intermolecular acylation of electron-deficient heteroarenes provides an easy access and a novel acylation method of heterocyclic compounds. The application of this CDC strategy for acylation strategy has been illustrated in synthesizing isoquinoline-derived natural products.
