Pteridines. 52. A Convenient Synthesis of 6-Formylpterin1

Abstract
6-Formylpterin has been prepared by a new and highly efficient procedure involving palladium-catalyzed coupling of 2-pivaloyl-6-chloropterin with styrene, followed by ozonolysis of the resulting 6-styryl derivative and acid hydrolysis of the 2-pivaloyl gorup.
