Biocatalytic 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 acylation of 2-methoxynaphthalene over zeolite catalysts
The Friedel–Crafts acylation of 2-methoxynaphthalene was carried out in the liquid-phase batch conditions using Hmordenite, H-beta and H-Y zeolite as catalysts. All the catalysts showed 35–40% conversion in the temperature range of 100–150◦C. 1-Acyl-2-methoxynaphthalene was formed as the primary product. When acetyl chloride was used as the acylating agent, a higher yield of 6-acyl-2-methoxynap...

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 کاملFacile acylation of glycerophosphocholine catalyzed by trifluoroacetic anhydride.
A simplified procedure for the synthesis of short acyl chain phosphatidylcholines is described. A mixed fatty acid-trifluoroacetic anhydride is used to acylate sn-glycero-3-phosphocholine (GPC) which has been dissolved in trifluoroacetic acid. Yields exceeding 70% are achieved in 30-min reaction time using 1.5 to 2.0 equivalents of mixed anhydride per, GPC hydroxyl. This allows a more economica...
