    摘要: There are described vinyl ether terminated ester oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise most often from the reaction of a dicarboxylic acid with a diol, although esters with triols and higher polyhydric polyols also are useful, especially where an extensively cross-linked product is desired. The carboxyl-terminated oligomeric esters are esterified with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and polyols, especially diols.

    摘要: A process for substantially enhancing the regio and stereoselective synthesis of 9-β-anomeric nucleoside analogs is described. The introduction of the sugar moiety onto a 6-substituted purine base was preformed so that only the 9-β-D- or L-purine nucleoside analogs were obtained. This regio and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-β-fluoro and 2′,3′-dideoxy-2′-β-fluoro purine nucleoside analogs in high yield without virtually any formation of the 7-positional isomers. The compounds are drugs or intermediates to drugs.
