Abstract
Methyl 1-aryl-3-benzoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates reacted with N′-(5,5-dimethyl-3-oxocyclohex-1-en-1-yl)benzohydrazides and N′-(5,5-dimethyl-3-oxocyclohex-1-en-1-yl)-2,2-diphenylacetohydrazide to give substituted N-[1′-aryl-3′-benzoyl-4′-hydroxy-6,6-dimethyl-2,4,5′-trioxo-1′,4,5,5′,6,7-hexahydrospiro[indole-3,2′-pyrrol]-1(2H)-yl]benz- and -diphenylacetamides.
