Alkylierungsmittel vom Typ der a-Brom-a-ethoxyessigsaurederivate [l] erwiesen sich in vorangegangenen Untersuchungen als geeignete Synthone zur reversiblen Blockierung von Carboxylgruppen iiber enzymatisch spaltbare Alkoxycarbonyl-ethoxymethylester [a] sowie zur Herstellung entsprechender bioabbauba
The title compound, C 18 H 20 ClNO 2 , has been synthesized by the reaction of 4-chlorobenzaldehyde, Meldrum's acid, dimedone and CH 3 NH 3 Cl(NaOAc) in ethanol under microwave irradiation. The pyridone ring adopts a screw-boat conformation and the cyclohexenone ring an envelope conformation.
## Abstract magnified image A relatively short and efficient method for the utilization of 4,6‐dichloro‐2‐methylthio‐5‐nitropyrimidine (**1**) in the synthesis of the poly substituted pyrrolo[3,2‐__d__]pyrimidin‐7‐one 5‐oxides (**6a**‐g) is reported. Some new 4‐substituted 6‐chloro‐2‐methylthio‐5‐
