A Simple Procedure to Prepare the Labile Stereoisomers of 5-Benzylidenepyrrolin-2-ones

The known Z-isomers of some N-unsubstituted 5-benzylidenepyrrolin-2-ones (2, 10, 12) change the configuration upon heating with oxalylchloride.Methanolysis of the intermediate imides (6, 8, 9) yields the corresponding E-isomers. - Key words: 5-Benzylidenepyrrolin-2-ones, 5-Benzylidenetetramic Acids, cis-trans Isomerisation
