Abstract

A crotonaldehyde type of condensation takes place in acetic anhydride between phenacylpyridinium iodide and al-D-glucose or al-D-galactose, to give mono-products, while al-D-mannose heptaacetate gives a di-product. If the heating time is increased, al-D-galactose is also found to give a di-product. Condensation of al-D-glucose with p-nitrolylpyridinium iodide in ethanol in the presence of pyridine gives a mono-product. In ethanol, the iodides obtained react with Ba (ClO4)2 to give perchlorates, deacetylated by perchloric acid in methanol.
