Descrição geral

Zinc chloride-catalyzed condensation of mesityl oxide with ethyl acetoacetate has been reported.

Aplicação

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

2,3,4,5-Tetrahydro-1,3,3-trimethyldipyrrin (1) is a crucial building block in the rational synthesis of chlorins and oxochlorins. The prior 5-step synthesis of 1 from pyrrole-2-carboxaldehyde (2) employed relatively simple and well-known reactions yet suffered from several drawbacks, including limited scale (>/= 0.5
