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 کاملEffective Friedel-Crafts acylation of biotin acid chloride in trifluoromethanesulfonic acid.
Biotin is one of the most useful tags in (bio)analytical science due to its specific interaction with avidin, but is not easy to convert because of its low solubility in most solvents. Friedel-Crafts acylation of biotin acid chloride in triflic acid was examined, and the synthesized derivatives had stronger affinity to avidin than biotin in a binding assay using 2-(4'-hydroxyphenylazo)benzoic a...
متن کاملAmmonium monovanadate: a versatile and reusable catalyst for Friedel-Crafts alkylation and Michael addition of indoles
Ammonium monovanadate (NH4VO3) has been devoted as an efficient, commercially available, eco-friendly and reusable catalyst for the synthesis of bis(indolyl)methanes (BIMs), oxindole derivatives and also Michael adducts of indoles at 50 °C under solvent-free conditions. The reusability of this solid acid catalyst in addition with its selectivity has also been examined.

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...
