  通过能量转移催化氢原子转移进行化学选择性喹啉和异喹啉还原

  摘要：

  烯烃和（杂）芳烃，要被还原还是保留？与传统工艺相比，在已报道的通过能量转移（EnT）催化实现的氢原子转移（HAT）方案中，喹啉的苯环比缺电子烯烃更容易被还原。此外，许多还原性不稳定部分，例如芳基碘化物、缺电子炔烃、苯磺酰胺和苄基醚，都与该方法兼容。

  Cyclization reactions of 2-alkynylbenzyl alcohol and 2-alkynylbenzylamine derivatives promoted by tetrabutylammonium fluoride

  摘要：

  The regioselectivity of the cyclization reaction of 2-ethynylbenzyl alcohol and 2-ethynylbenzylamine derivatives promoted by TBAF was investigated. Six-membered ring derivatives were obtained from the compounds, which have a butyl group on the triple bond. Whereas five-membered ring products were afforded from the substrates having hydrogen or aromatic substituents. on the acetylene moiety. It was also concluded that both the tetrabutylammonium cation and fluoride anion were essential for the cyclization. Thus, the actual mechanism and catalytic cycle were also suggested.

  DOI：10.1248/cpb.48.669

  日期：——

  In order to elucidate the reaction mechanism of the cyclization between an ethynyl group and an imino group at the ortho-position on an aromatic ring to afford isoquinolines, reaction of 2-ethynylbenzaldehydes under various conditions was examined. It is concluded that reaction proceeds via an ionic process and the isoquinoline 4-hydrogen atom derives from the solvent. In addition, it was found taht 2-ethynylbenzaldehyde O-methyloximes underwent cycliazation in the presence of primary and secondary alcohols to give 3-substituted isoquinolines.

  The activity of a simple, commercially available copper salt, [Cu(NCMe)4](BF4) in intramolecular hydroamination reactions of alkynes and allenes is presented. Reactions were successfully carried out in technical acetonitrile in the presence of air. While attempts of alkene hydroamination failed, this catalysts was also found active in intermolecular aza-Michael reactions.
