Abstract
IN a recent communication, Davoll, Brown and Visser1 have described two forms of 1 : 2 : 3 : 5 tetra-acetyl D-ribofuranose. The form first obtained had melting point 56°–58° and was probably identical with the compounds of Howard, Lythgoe and Todd2, and of Bredereck and Hoepfner3. This substance changed spontaneously into another, melting point 85°, proved to be identical with the 1 : 2 : 3 : 5 tetra-acetyl D-ribofuranose of Zinner4. The transformation was reported to be accompanied by a change in specific rotation from [α]20D − 3.6° to − 13.5° (in methanol).
