Abstract
NEW MATERIAL:Dicyandiamidine pantoate.
USE: A synthetic intermediate for pantolactone. Veryl useful for selectively preparing the D(-)-pantolactone useful as an intermediate for preparing a D(+)-pantothenate salt, D(+)-pantethine, etc. remarkably useful in the vitaminic activity.
PROCESS: Pantolatone is reacted with dicyandiamidine in water or a hydrous organic solvent to give dicyandiamidine pantoate. Alternatively, a metllic salt of pantoic acid is reacted with a salt of dicyandamidine in water and/or an organic solvent to afford the dicyandiamidine pantoate. The resultant pantoate is then crystallized if necessary in water or an organic solvent to give an optically active substance selectively.
