Higher-carbon Sugars from D-Glucose

Here the synthesis led to an a-galaheptose (amorphous) and from it a galaoctose (crystalline) was prepared. Many years later the a-galaheptose was crystallized. The 9-galaheptose crystallized in Fischer s research, and the epimeric character of the two galaheptoses was made highly probable by his interconversion of their aldonic acids on heating with aqueous pyridine.
