Application of the controlled hydrolysis, with mercuric chloride and cadmium carbonate, to acetylated sugar mercaptals' having the cis-configuration on carbon atoms two and three, such as mannose, rhamnose and a-glucoheptose, has led to impure sirupy products instead of the desired crystalline aldehydo-sugar acetates. The new synthesis of aldehyde-sugar acetates reported from this Laboratory2 offered a different method of approach which has ...
