New catalytic oxidation of trifluoromethyl carbinols by a ruthenium(II) complex
摘要:
The first catalytic oxidation of trifluoromethyl carbinols has been accomplished by a novel ruthenium(II) complex using sodium periodate as an oxidant. Trifluoromethyl ketones were obtained under mild conditions and in excellent yields. (C) 2000 Elsevier Science Ltd. All rights reserved.
The trifluoromethylation of benzoic acids with TMSCF3 was achieved through nucleophilic substitution with the use of anhydrides as an in situ activating reagent. Under the reaction conditions, a wide range of carboxylic acids including the bioactive ones worked well, thus providing a facile and efficient method for preparing aryl trifluoromethyl ketones from the readily available starting materials

The examination of a series of trifluoromethyl ketone inhibitors of Fatty Acid Amide Hydrolase (FAAH, oleamide hydrolase, anandamide amidohydrolase) is detailed in efforts that define structural and conformational properties that contribute to enzyme inhibition and substrate binding. The results imply an extended bound conformation, highlight a role for the presence, position, and stereochemistry of
