DEFINITION

Classification: 435/73

Preparing S-glycoside (e.g, lincomycin, etc.):

(under subclass 72) Processes wherein the product synthesized is a thioacetal derivative of a cyclic form of sugar in which the hydrogen atom of the hemithioacetal sulfhydryl group has been replaced by an alkyl, aralkyl, or aryl group.

(1) Note. An S-glycoside is a compound having a sugar moiety connected to an aglycone moiety via a sulfur.

(2) Note. The aglycone is a nonsaccharide material, e.g., benzene, indoxyl, anthracene, etc.

(3) Note. On complete hydrolysis S-glycosides yield one or more monosaccharides, and a mono or a polyhydric thiol or thiol phenol.

(4) Note. The cyclic sugars referred to in the definitions are normally pyranoses or furanoses.

(5) Note. Gyclosides derived from aldoses are referred to as aldosides, and those from ketoses are ketosides.
