A better understanding of the role of PPAR in insulin action system will be critical in developing more efficacious and safe agent s that act on PPAR and benefit patients with type 2 diabetes. The main content is followed: Synthesis and analysis of 1,3-dicarbonyl compounds. Make use of easily available cheap reagent such as 2-naphthol, 6-hydroxyquinoline, 1,2-dibromoethane, 4- hydroxybenzaldehyde, dimethyl malonate, 2-{4- [(2-napthoxy)ethoxyl] benzyl} malonates and 2-{4 [(1,2,3,4-tetrahydro-6 -quinolinoxy)ethoxyl] benzyl } malonates were synthesized through 6-8 steps in virtue of Williamson, Knoevenagel reaction, Pd/C catalyzed hydrogenation with mild conditions and high yield. The total yield of 40-50%.
