Die Umsetzung von Azlactonen mit CH-aciden Verbindungen. 2. Mitteil. (1)

Alkyl cyanoacetate, malonate, acetoacetate and methylsulfonyl acetic acid ethyl ester are acylated by alkylidenazlactones.The acyl compounds easily form alkylidenetetramic acids by condensation.The acylcyanoacetates 2 isomerize into aminopyrrolines 3 via acid catalysis.
