Thus, D-erythrose and D-threose are obtained in high yields from the arabinose
and xylose derivatives, and arabinose from the mannose mercaptal. The ring in
scyllo-myo-inosose has been broken, by conversion to the mercaptal, and ...

Chemistry of The Carbohydrates
Acetal and Mercaptal Derivatives of Acyclic Sugars A. Mercaptals. In their
reaction with alcohols in the presence of hydrogen chloride, the sugars differ from
the simple aldehydes in forming mixed acetals (glycosides) rather than dialkyl
acetals.

Wolfrom was interested in employing his sugar mercaptal reaction for study of the
degradation of cellulose. The proportion of sulfur found in the intermediates
isolated was to be used for estimating the extent of degradation. Sowden became
