Investigations on substitution in the sugar group

Abstract

1. The analysis of the acetone compounds derived from the dibenzyl mercaptals of glucose, galactose and mannose is described.2. From the results it is concluded that the mono-methyl compounds are probably derived in each case from monoacetone hexose dibenzyl mercaptals, although the precise formulation of these compounds is in doubt.3. It is shown that the dibenzyl mercaptals of 2- methyl glucose, 4- methyl glucose and 6- methyl galactose, on condensation with acetone, appear to yield only monoacetone derivatives.
