Catalytic Enantioselective α‐Fluorination of 2‐Acyl Imidazoles via Iridium Complexes
Chemistry - an Asian Journal, 2016The first highly enantioselective α-fluorination of 2-acyl imidazoles utilizing iridium catalysis has been accomplished. This transformation features mild conditions and a remarkably broad substrate scope, providing an efficient and highly ...

A series of analogs of N-benzylimidazole was prepared and tested for hypolipidemic activity. Both plasma cholesterol and triglyceride-lowering activity were found in several members of the series. The most active compounds were N-3-methoxy-, N-4-methoxy-, and N-4-methylbenzylimidazole. Structure-activity relationships are discussed.

Abstract Myoglobin is photooxidized when exposed to visible light in the presence of a sensitizer. In 8 M urea medium this photooxidation is followed by photodynamic interpeptide crosslinking. A partial inhibition of crosslinking is caused by lysine, mercaptoethanol and hydroxylamine, and by amidination of NH2 groups in the protein molecule. Complete
