Abstract

NEW MATERIAL:A compound shown by the formula I (R<1> is acyl; R<2> is H, or OH). EXAMPLE:N<4>-Behenoyl-1-[(1R,2S,3R)-2,3-dihydroxy-4-hydroxym-et-hyl-4- cyclopen ten-1-yl]cytosine. USE:An antitumor agent or an antiviral agent. PREPARATION:A compound shown by the formula II is reacted with a carboxylic acid compound shown by the formula R<1>-OH or its reactive derivative in an inert solvent at 0 deg.C - the reflux temperature of a solvent for several hours - tens hours, to give a compound shown by the formula I. A condensation agent may be used.
