First, 2-aryl-5-methoxy oxazoles were prepared by the method of Wipf’s protocol*) from methyl N-acyl glycine methyl esters in the presence of Et3N in DCE with PPh3 and I2 at room temperature for 19-24hr. These reactions proceeded in mild condition and gave 2x to 80-97% yield by column chromatography. Then, we attempted to apply the method of Friedel–Crafts acylation in order to synthesis of acylated oxazoles from 5-methoxy -2-phenyl oxazole (*). The normal conditions which used Lewis acid…

Bromination of trans-cinnamic acid Purpose and Introduction The halogenation of of trans-cinnamic acid using pyridinium tribromide was connected in the organic solvent glacial acetic acid in order to verify and test which addition mechanism the reaction would follow. In the anti-addition mechanism, bromines attach themselves on opposite sides of the alkene functional group in a compound. In a syn-addition, the attach to the same side of the alkene. The reaction synthesis was completed by using a…
