  the synthesis of 3-amino-1,4-diynes. Although metal-catalyzed A3-coupling reactions have been extensively used to synthesize various propargylamines, the A3-coupling for the synthesis of 3-amino-1,4-diynes has been rarely reported. In this study, various symmetrical 3-amino-1,4-diynes were synthesized by the sequential Cu-catalyzed dealkynylation of propargyl aldehydes followed by A3-coupling. Unsymmetrical

  Sequential addition reactions of two molecules of Grignard reagents to thioformamides were found to yield tertiary amines in an efficient manner. The addition of two different Grignard reagents can be accomplished by using one equivalent of arylmagnesium reagent in the first step. In the second step, a variety of reagents such as alkyl, alkenyl, aryl, and alkynyl reagents were used to afford the corresponding

  The reaction of thioiminium salts with zinc acetylides took place at 60 °C to give 3-amino-1-sulfenyl-1,4-enynes in moderate to good yields. Two molecules of acetylides were incorporated into the products. Nucleophilic attack of zinc acetylides to thioiminium salts may initially occur to form alkynyl S,N-acetals, followed by their [1,3]-rearrangement to give 3-sulfenyl-1-aminoallenes.

• Copper-Catalyzed Coupling Reaction of C−OMe Bonds Adjacent to a Nitrogen Atom with Terminal Alkynes

  日期：2010.7.2

  The cross coupling of the C-OMe bond adjacent to a nitrogen atom in dialkoxy-N,N-dialkylmethanamines with terminal alkynes was efficiently approached in the presence of copper catalyst under mild conditions to give 3-amino-1,4-diynes in good yields. The reaction is promoted by phosphine ligands and the chemistry provides a simple and efficient route to 3-amino-1,4-diynes. Importantly, the Michael addition occurred with as-prepared 3-amino-1,4-diynes to give the useful Michael-adducts containing tert-alkylamines in a very convenient way. Further studies revealed that (E)-1,5-diarylpent-1-en-4-yn-3-one was formed through the rearrangement by using the neutral alumina column, and the corresponding imine 2-(1,5-diphenylpent-2-en-4-ynylideneamino)ethanol was obtained in the presence of AgOTf.
