Zinc chloride-catalyzed condensation of mesityl oxide with ethyl acetoacetate has been reported.
Application
Mesityl oxide has been used:
- in the synthesis of 2,3,4,5-tetrahydro-1,3,3-trimethyldipyrrin, a crucial building block in the rational synthesis of chlorins and oxochlorins
- as neutral marker in the preparation of imidazole-coated capillary column for electrophoresis
