HETEROCYCLIZATION USING PHASE TRANSFER CATALYSIS: A SIMPLE AND CONVENIENT SYNTHESIS OF 2-AMINO-1-ARYL-5-OXO-4,5-DIHYDRO-1H-PYRROLE-3-CARBONITRILES
摘要:
A simple and convenient synthesis of 2-amino-1-aryl-5-oxo-4,5-dihydro-1H-pyrrole-3-carbonitriles has been studied with and without phase transfer conditions. The best results were obtained using 18-crown-6 under solid-liquid phase transfer conditions in acetonitrile.
