2-Ethyl-2-oxazoline oxazolines towards ring-opening by chloride ions during protonation of the imine nitrogen. The direct reaction of propanoyl chloride with 2-chloroethylamine hydrochloride in the presence of triethylamine avoids the formation of water. Propanal reacts with 2-aminoethanol in "t"-butanol to 2-ethyl-2-oxazoline in the presence of the iodinating reagent 1,3-diiodo-5,5-dimethylhydantoin (DIH) and potassium carbonate. 2-Ethyl-2-oxazoline is a readily water-soluble, colorless liquid which is also soluble in a variety of organic solvents and possesses an amine-like smell. Aqueous solutions react alkaline. The compound is stable in alkaline but hydrolyses under acid action. In anhydrous form, 2-ethyl-2-oxazoline is mostly used as a monomer. The cationic
Ethyl caffeate skin. Ethyl caffeate administered intraperitoneally in rats previously is able to prevent the dimethylnitrosamine-induced loss in body and liver weight, as well as to reduce the degree of liver injury. It can be considered as a promising natural compound for future application in chronic liver disease. Pharmacophore modeling, molecular docking, and molecular dynamics simulation studies also indicate that ethyl caffeate is a potential inhibitor of the aldosterone synthase (CYP11B2), a key enzyme for the biosynthesis of aldosterone, which plays a significant role for the regulation of blood pressure. Ethyl caffeate reacts with methylamine to produce green pigments. Ethyl caffeate Ethyl
