Substituted γ-Lactones: On the Structural Elucidation of the Reaction Products from 4-Aroyl-3-hydroxy-2(5H)-furanones and 1,2-Diamines

Zimmer, Hans,Amer, Adel,Ho, Douglas,Palmer-Sungail, R.

, p. 1501 - 1510 (2007/10/02)

The reaction pathway of 4-aroyl-3-hydroxy-2(5H)-furanones 1 with diamines depends on the nature of the amine as well as on the applied reaction conditions.Thus, the reaction of 1a-d with 5,6-diamino-1,3-dimethyluracil 5 led to the formation of two isomeri
