Abstract
An effective route to novel 5-hydroxy-1,5-dihydro-2H-pyrrol-2-one is described which involves the reaction of an enamine, derived from addition of a secondary amine to dibenzoylacetylene, with an arylsulfonyl isocyanate.
Key words
dibenzoylacetylene - secondary amine - isocyanate - 5-hydroxy-1,5-dihydro-2H-pyrrol-2-one - multicomponent reaction
