DEFINITION

Classification: 435/85

N-glycoside:

(under subclass 84) Processes wherein the product synthesized is a glycosidic derivative of the cyclic forms of saccharides or polysaccharides in which the aglycone portion is attached through nitrogen to the saccharide moiety by substituting it for the hemiacetal hydroxyl of the sugar.

(1) Note. The aglycone can be noncyclic.

(2) Note. N-glycosides in which the aglycone is purine or pyrimidine in which the ring structure is intact are provided for in subclasses 87 and 89. Compounds such as those below are not considered to be within this meaning and thus, are here in subclass 85 [figure] [caption]6-azauracil riboside [figure] [caption] or 8-azaguanine riboside
