Abstract
1-(3-Aminopropyl)-5-aryl-4-acyl-3-hydroxy-3-pyrrolin-2-ones (I–X) were prepared via reaction of methyl acylpyruvates and a mixture of aromatic aldehyde and 1,3-diaminopropane in a 1:1:1 molar ratio. The products were converted to hydrochlorides XI–XV in 48–90% yields. 1,3-Di(4-acetyl-3-hydroxy-2-oxo-5-phenyl-3-pyrrolin-1-yl)propane (XVI) was produced in 16% yield via reaction of methyl acetylpyruvate with a mixture of benzaldehyde and 1,3-diaminopropane in a 2:2:1 molar ratio. The biological activity of the 12 products was studied.
