Abstract
Substituted alkyl 4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates reacted with urea to give alkyl 2-(carbamoylamino)-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrole-2-carboxylates which underwent intramolecular cyclization to 8-hydroxy-1,3,6-triazaspiro[4.4]non-8-ene-2,4,7-triones by the action of sodium methoxide.
