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 four-component reaction of arylcyclopropanes, nitriles, carboxylic acids and <i>N</i>-fluorobenzenesulfonimide: facile synthesis of imide derivatives
An unprecedented copper-catalyzed four-component reaction of arylcyclopropanes, nitriles, carboxylic acids and N-fluorobenzenesulfonimide (NFSI) has been successfully developed, which represents the first example of a four-component reaction of non-donor–acceptor cyclopropanes. A wide range of imide derivatives were efficiently synthesized in excellent yields under mild conditions.
