Silver-catalysed intramolecular hydroamination of alkynes with trichloroacetimidates.
نویسندگان
چکیده
Silver(I) complexes catalyse the intramolecular addition of trichloroacetimidates to alkynes. In the absence of a ligand, the selectivity of the reaction is dependent upon the nature of the counter-anion and solvent. The introduction of non-chelating nitrogeneous ligands suppresses competitive Brønsted acid catalysis, improving the yield and selectivity of the reaction.

متن کاملDirect access to pyrido/pyrrolo[2,1-b]quinazolin-9(1H)-ones through silver-mediated intramolecular alkyne hydroamination reactions
We report a synthetic methodology for the construction of the fused heterocyclic compounds pyrido[2,1-b]quinazolin-9(1H)-ones and pyrrolo[2,1-b]quinazolin-9(1H)-ones through an AgOTf-catalyzed intramolecular alkyne hydroamination reaction. The methodology is applicable to a wide scope of substrates and produces a series of fused quinazolinone heterocycles in good to excellent yields.

In recent years, considerable effort has been devoted to develop methodologies which reduce multi-step transformations into one-step tandem processes. In this regard, the use of multifunctional catalysts, which promote sequential reaction steps without additional requirement of additives and/or co-catalysts, provides an effective way while taking care of two most basic challenges faced by a syn...
متن کاملThe catalytic hydroamination of alkynes.
The direct addition of ammonia or primary and secondary amines to non-activated alkenes and alkynes is potentially the most efficient approach towards the synthesis of higher substituted nitrogen-containing products. It represents the most atom economic process for the formation of amines, enamines and imines, which are important bulk and fine chemicals or building blocks in organic synthesis. ...
