A Convenient Method for the Synthesis of Dehydroquinic Acid
摘要:
A convenient synthesis of dehydroquinic acid and its corresponding methyl ester are described. Protection of the trans diol of quinic acid, followed by PCC oxidation gave fully protected dehydroquinic acid. This gave methyl dehydroquinate on mild, acid catalyzed hydrolysis. Ester hydrolysis then gave potassium dehydroquinate which was treated with amberlite to afford dehydroquinic acid.

The 2ax-proton of 3-dehydroquinicacid is selectively exchanged for deuterium at pH 7·0 in deuterium oxide to give (2S)-2-deuterio-3-dehydroquinic acid (XIV)(0·65 atom deuterium). Structure (XIV) was proved by degradation to citric acid and equilibration with the enzyme aconitase. Catalytic deuteriogenolysis of (2R)-2-bromotriacetylquinide gave (2RS)-2-deuteriotriacetylquinide, which was converted

observation of kinetic isotope effects using this substrate with both Neurospora crassa and Escherichia coli chorismate synthases. The magnitude of the effects were (D)(V) = 1.08 +/- 0.01 for the N. crassa enzyme and 1.10 +/- 0.02 on phosphate release under single-turnover conditions for the E. coli enzyme. The effects are best rationalised as substantial secondary beta isotope effects. It is most likely
