employed has been a solution-phase parallel synthesis based on the coupling of three thymine-derived acids [4-(thymin-1-yl)butyric acid (I), [4-(thymin-1-yl)-butyrylamino]aceticacid (II) and 6-(thymin-1-yl)hexanoic acid (III)] with different commercially available primaryamines that carry cyano and/or phenyl groups. The couplings were performed in good yields (from 60% to 90%), with the exception of those

A novel methodology for the formation of blockcopolymers has been developed that combines ring-opening metathesis polymerization (ROMP) with functional chain-transfer agents (CTAs) and self-assembly. Telechelic homopolymers of cyclooctene derivatives end-functionalized with hydrogen-bonding or metal-coordination sites are formed through the combination of ROMP with a corresponding functional CTA.
