title: The synthesis of 3-deoxyheptulosonic acid 7-phosphate.
abstract: 3-Deoxyheptulosonic acid 7-phosphate was obtained by a one-step chemical synthesis through condensation of oxalacetate with erythrose 4-phosphate. This reaction occurs at measurable rates only in the presence of a metal ion; Co2+ and Ni2+ are the most effective catalysts. The Co2+ catalyzed condensation of oxalacetate and erythrose 4-phosphate proceeds at room temperature and neutral pH. Since erythrose 4-phosphate can be replaced by any free aldehyde tested thus far, this type of a homogeneous catalysis opens new synthetic routes to alpha-keto-gamma-hydroxy-fatty acids and their derivatives.
