Fluorinated methoxy arenes are emerging as important motifs in both agrochemicals and pharmaceuticals. A novel technique for the synthesis of monofluoromethoxy arenes through the direct fluorodecarboxylation of carboxylic acids was developed that uses photosensitizers and N-fluorobenzenesulfonimide (NFSI). Utilization of the oxidatively mild fluorine transfer agent NFSI enabled the synthesis of fluoromethyl ethers that were previously inaccessible with decarboxylative fluorinations performed with Selectfluor. Mechanistic studies are consistent with the photosensitizer effecting oxidation of the aryloxyacetic acid.
ABSORBABLE BRANCHED POLYESTERS AND POLYURETHANES

Paragraph 0204-0206, (2014/05/25)
The present invention relates to the discovery of a new class of hydrolysable isocyanates, hydrolysable branched polyols and branched absorbable polyesters and polyurethanes prepared therefrom. The resultant absorbable polymers are useful for drug delivery, stents, highly porous foam, reticulated foam, tissue engineering, tissue adhesives, adhesion prevention, bone wax formulations, medical device coatings, surface modifying agents and other implantable medical devices. In addition, these absorbable polymers can have a controlled hydrolytic degradation profile.

Evaluation of nitrate-substituted pseudocholine esters of aspirin as potential nitro-aspirins

Herein we explore some designs for nitro-aspirins, compounds potentially capable of releasing both aspirin and nitric oxide in vivo. A series of nitrate-bearing alkyl esters of aspirin were prepared based on the choline ester template preferred by human plasma butyrylcholinesterase. The degradation kinetics of the compounds were followed in human plasma solution. All compounds underwent hydrolysis rapidly (t1/2 ～ 1 min) but generating exclusively the corresponding nitro-salicylate. The one exception, an N-propyl, N-nitroxyethyl aminoethanol ester produced 9.2% aspirin in molar terms indicating that the nitro-aspirin objective is probably achievable if due cognisance can be paid to the demands of the activating enzyme. Even at this low level of aspirin release, this compound is the most successful nitro-aspirin reported to date in the key human plasma model.
