  可见光促进四氢异喹啉在流动中的光氧化还原C（sp3）–H键功能化

  摘要：

  流动中进行的有机催化和可见光氧化还原催化的合并，允许在正式的C–H氧化/曼尼希反应中使用各种官能化的N-芳基取代的四氢异喹啉（THIQs）。几种N-芳基取代的THIQ的Strecker型官能化和铜催化的炔基化也已成功进行，从而获得了有价值的高效率产品。事实证明，使用定制的多孔聚合物型微反应器对于C–H氧化步骤和整体反应性能至关重要。

  three component, four-centered A3 coupling strategy has been developed for the synthesis of a novel series of 1-arylethynyl-tetrahydro-β-carboline derivatives in good yields with high selectivity. This method is also useful for the preparation of 1-arylethynyl tetrahydroisoquinolines, which can be used for the synthesis of biologically active molecules such as homolaudanosine, dysoxyline, methopoline

  Our previous studies into visible-light-mediated aza-Henry reactions demonstrated that molecular oxygen played a vital role in catalyst turnover as well as the production of base to facilitate the nucleophilic addition of nitroalkanes. Herein, improved conditions for the generation of iminium Ions from tetrahydroisoquinolines that allow for versatile nucleophilic trapping are reported. The new conditions provide access to a diverse range of functionality under mild, anaerobic reaction conditions as well as mechanistic insights into the photoredox cycle.

  Solvent-free asymmetric cross-dehydrogenative-coupling (CDC) reaction between the sp(3) C-H bond of prochiral CH2 and terminal alkynes was first studied under High-Speed Ball-Milling conditions. A series of optical active 1-alkynyl tetrahydroisoquinoline derivatives were achieved by using recoverable copper balls together with PyBox chiral ligand in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). All coupling products were obtained in good yields at short reaction time with enantiomeric excesses up to 79%. (C) 2013 Elsevier Ltd. All rights reserved.
