Abstract
Compounds 4-arylmethylene-2-methyl-2-oxazolin-5-ones and 4-arylmethylene-2-styryl-2-oxazolin-5-ones react with primary aromatic amines in the presence of anhydrous zinc chloride to give the corresponding 4-arylmethylene-2-methyl-2-imidazolin-5-ones and 4-arylmethylene-2-styryl-2-imidazolin-5-ones (5) respectively. Treatment of 5 with phosphorus pentasulfide gives the corresponding 2-imidazoline-5-thiones. Reaction of 4-arylmethylene-2-phenyl-2-oxazolin-5-ones with hydroxylamine hydrochloride gives the corresponding imidazolinones which was reacted with alkyl halides and acid chlorides to give the corresponding ethers and esters respectively. Structures of the resulting products have been characterized on the basis of elemental analysis, IR, and UV data.
