Synthesis by a novel cyclization reaction and crystal and molecular structure of 4-ethyl-1-isopropyl-3-[(phenylcarbamoyl)methyl]-3-pyrrolin-2-one
Abstract
The title compound (I) was synthesized by reaction of N-butylidenepropylamine and N-phenylmaleimide at room temperature and without added catalysts: a reaction mechanism is suggested. The structure of (I) was unambiguously determined by X-ray diffraction analysis.
