Abstract

Abstract 3-Pyrrolcarbonsäureester 4 sind aus α-Nitroolefinen 1 und Acetessigestern 2 nach zwei Methoden zugänglich: a) Man stellt aus 1 und 2 4, 5-Dihydro-5-methylenamino-3- furancarbonsäureester 3 her und hydrolysiert diese, b) die Nitronsäuren 8, Addukte aus 1 und 2, liefern mit verschiedenen Reduktionsmitteln die Heterocyclen 4.
