An asymmetric Brønsted acid-catalyzed Friedel–Crafts reaction of indoles with cyclic N-sulfimines
The indole skeleton is the most universal heterocycle structure in nature and is well established as a privileged scaffold; it is commonly encountered in many biologically active natural products and pharmaceutical compounds. Owing to the great structural diversity of biologically active indoles, indole units are of great importance in medicinal chemistry and are widely used in the pharmaceutic...
متن کاملSquaramide-catalyzed enantioselective Friedel-Crafts reaction of indoles with imines.
Chiral squaramides are highly enantioselective catalysts for Friedel-Crafts reaction of indoles with N-tosyl imines, affording 3-indolyl methanamine products in 85-96% yields and 84-96% ees.
متن کاملChiral Brønsted Acid Catalyzed Enantioselective aza-Friedel-Crafts Reaction of Cyclic α-Diaryl N-Acyl Imines with Indoles.
Asymmetric addition of indoles to cyclic α-diaryl-substituted N-acyl imines, which are generated in situ from 3-aryl 3-hydroxyisoindolinones, is described. The transformation proceeds smoothly with a broad range of indoles and isoindolinone alcohols using a SPINOL-derived chiral Brønsted acid catalyst to afford α-tetrasubstituted (3-indolyl)(diaryl)methanamines in excellent yields and enantiose...
متن کاملBiocatalytic Friedel–Crafts Acylation and Fries Reaction
The Friedel-Crafts acylation is commonly used for the synthesis of aryl ketones, and a biocatalytic version, which may benefit from the chemo- and regioselectivity of enzymes, has not yet been introduced. Described here is a bacterial acyltransferase which can catalyze Friedel-Crafts C-acylation of phenolic substrates in buffer without the need of CoA-activated reagents. Conversions reach up to...
متن کاملFriedel-Crafts Alkylation of Alkenes: Ethylaluminum Sesquichloride Induced Alkylations with Alkyl Chloroformates.
The formal addition of propane to nonactivated double bonds can be achieved with isopropyl chloroformate (2) in the presence of Et(3)Al(2)Cl(3). Thus, a 1:1 mixture of 10-isopropyloctadecanoic acid (3) and the 9-regioisomer is formed from oleic acid (1). The reaction may also be carried out with 1-alkenes by the addition of triethylsilane as a hydride donor.
