PROBLEM TO BE SOLVED: To efficiently obtain the subject product useful as a synthetic intermediate for medicines and agrochemicals in high yield by carrying out Friedel-Crafts alkylation reaction by using various kinds of perfluoroalkanesulfonylimide group-containing compounds as a catalyst.MIKAMI KOICHI...
The Friedel-Crafts Alkylation represents one of the six classes of electrophilic aromatic substitution reactions. The diversity and scope of Friedel-Crafts Alkylations is broad.
Hydrogen bondMetal-templateIridiumAn asymmetric Friedel–Crafts alkylation of indoles with 2-nitro-3-arylacrylates catalyzed by a metal-templated hydrogen bonding catalyst has been established. The asymmetric induction relies on chirality transfer solely from the octahedral metal stereocenter via three ...
