- In each experiment the progress of the reaction and the purity of the products obtained were determined by tic on silica gel plates using chloroform-methanol-water 1:1:0.3 as solvent systems
- The use of tributylamine in place of sodium hydroxide as the base and substitution of pyridine for acetone-water as the solvent gave other sugar derivatives but no 1 or 4

- A brown precipitate was obtained in each case. However, no 1 was obtained on hydrolysis of the solid with lithium hydroxide
- When the potassium salt was used, the final product was difficult to separate from inorganic potassium salts
