A copper-catalyzed 1,3-aminothiocyanation of arylcyclopropanes with N-fluorobenzenesulfonimide (NFSI) and trimethylsilyl isothiocyanate (TMSNCS) has been developed for the first time, efficiently synthesizing a series of γ-aminothiocyanate derivatives in moderate to excellent yields from readily available substrates under mild conditions. The practicability of the reaction was demonstrated by gram-scale
A facile approach for the synthesis of enantiopure γ-amino nitriles by copper-catalyzed aminocyanation of arylcyclopropanes is disclosed, which undergoes the highly enantioselective ring-opening reaction of cyclopropanes. The strategy utilizes N-fluorobenzenesulfonimide as nucleophilic nitrogen source as well as oxidant and trimethylsilyl cyanide as the other nucleophile, and it probably operates via
A copper-catalyzed 1,3-aminoalkynylation or 1,3-aminobromination of arylcyclopropane with N-fluorobenzenesulfonimide (NFSI) and trimethoxy[(trimethylsilyl)ethynyl]silane or LiBr have been successfully developed. Through this strategy, a wide range of γ-alkylnyl-/γ-bromino-γ-branched amine derivatives were efficiently synthesized in good yields under mild conditions.
