Synthesis of N-[4-(2'-[18F]fluoroalkoxybenzoyl)]- And N-(3-[123I]iodo-4-methoxybenzoyl)pyrrolidin-2-ones as potential brain imaging agents

– The microfluidic synthesis of promising brain imaging PET agents N-[4-(2’-[18F]fluoroalkyloxybenzoyl)]pyrrolidin-2-ones 13a-c was accomplished by nucleophilic radiofluorination of the corresponding tosylate precursors 9a-c with Kryptofix-pota

Syntheses and Reactions of (Trimethylsiloxy)benzoyl Chlorides

The (trimethylsiloxy)benzoyl chlorides 1-7 are easily to obtain under mild conditions from silylated hydroxybenzoic acids by means of thionyl chloride.Whereas these acid chlorides are stable at room temperature, they undergo condensation polymerisation at temperatures above 100 deg C.Reactions with various nucleophils, such as thioalcohols, phenols, amines, N,O-bis(silylated)amino acids and N-silylated lactams were investigated.With hexamethyldisilazane and thionyl chloride the (trimethylsiloxy)benzonitriles 21, 22 are accessible, and by means of trimethylsilylazide the (trimethylsiloxy)phenyl isocyanates 23-25 were obtained.Conversion with phenyl carbazate and subsequent silylation lead to the 2-(trimethylsiloxy)phenyl-1,3,4-oxadiazol-5-ones 27a-c.
