TRANSITION FROM 3-INDOLECARBALDEHYDES TO 4-OXO-1,4-DIHYDRO-δ-CARBOLINES THROUGH α-(3-INDOLYL)-N-ARYLNITRONES

α-(3-Indolyl)-N-arylnitrones, obtained from 3-indolecarbaldehydes and arylhydroxyamines, are converted by the action of sodiomalonic ester into N-aryl-N-(3-indolyl)-β-aminopropenoic esters.The latter are converted by the action of acetic or trifluoroaceti
