  objective of this work was to develop persulfate mediated oxidative transformations that can be performed nearly at room temperature using water as a solvent. This report describes modified Minisci aroylation of isoquinolines with arylglyoxylic acids using choline persulfate and its pre-composition (choline acetate and K2S2O8) in water at 40 °C. A few other nitrogen heterocycles were also utilized affording

  金属过硫酸盐介导的热氧化有机转化总是需要更高的温度并且经常使用有机溶剂。这项工作的目的是开发过硫酸盐介导的氧化转化，它可以在几乎室温下使用水作为溶剂进行。本报告描述了使用过硫酸胆碱及其预组合物（醋酸胆碱和 K 2 S 2 O 8) 在 40 °C 的水中。还使用了一些其他氮杂环，以良好到极好的产率提供各种芳酰化产物。与可能产生金属盐副产物的金属过硫酸盐不同，本文报道的化学的一个关键特征包括使用含有可生物降解胆碱的环境无害的过硫酸胆碱作为抗衡阳离子，Minisci 反应在 40 °C 下作为唯一的溶剂证明，和过硫酸盐的非常规活化。

  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

• 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.
• A Transition Metal-Free Minisci Reaction: Acylation of Isoquinolines, Quinolines, and Quinoxaline
  作者：Yogesh Siddaraju、Manjunath Lamani、Kandikere Ramaiah Prabhu

  DOI：10.1021/jo500294z

  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.
