A versatile polycationscaffold that can easily be modified with targeting ligands has been designed, synthesized, and characterized. A series of galactose‐containing polymers has been produced to demonstrate the ease of modification of this polynucleotide delivery vehicle motif via the click reaction and to study how various structural modifications affect recognition by ASGPr on hepatocytes. A small

5-chloropentyne and propargyl bromide with diethyl 2-ethyl-2-sodiomalonate (DESM) provided diethyl 2-ethyl-2-(1-pentyn-5-yl)malonate (3) and diethyl 2-ethyl-2-propargylmalonate (4), respectively. Similar condensation of DESM with (E)-(5-iodo-1-penten-1-yl)boronic acid (9) or the reaction of catecholborane with 3 provided diethyl (E)-2-ethyl-2-(1-borono-1-penten-5-yl)malonate (8). The direct sodium iodide-chloramine-T

A novel recyclable catalyst for chelation-assisted hydroacylation of an olefin with a primary alcohol was developed by utilizing a hydrogen-bonding self-assembly motif consisting of a barbiturate bearing 2-aminopyridin-4-yl group and 5-hexyl-2,4,6-triaminopyrimidine. This was further applied to a mixed catalyst system to recycle both organic and organometallic catalysts.
