Abstract
NEW MATERIAL:A compound of formulaI(R is alkyl of 4 or more carbon atoms including n-butyl, isobutyl, n-pentyl, isopentyl, n-hexyl).
EXAMPLE: n-Butyl-β-D-ribofuranoside.
USE: Antiallergic, carcinostatic agent: it selectively suppresses the production of antibody immunogloblin E causing allergic diseases, but not immunogloblins governing immunological reactions in normal human bodies, thus showing intrinsically antiallergic actions.
PREPARATION: The reaction between D-ribose of formula II and an alkyl alcohol of formula III (butanol, methylpropanol, pentanol) is conducted in the presnce of an acid such as sulfuric, hydrochloric, formic or acetic acid at room temperature or under heating for 10W24hr to give the compound of formulaI.
