substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y14 activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y14 potency. For example, the [5′′]ribose derivative

the leading candidate for the first biopolymer of life. Aminooxazolines have recently emerged as key prebiotic ribonucleotide precursors, and here we develop a novel strategy for aminooxazoline-5′-phosphate synthesis in water from prebiotic feedstocks. Oxidation of acrolein delivers glycidaldehyde (90%), which directs a regioselective phosphorylation in water and specifically affords 5′-phosphorylated

Phosphorylation of 5,6-anhydro-3-O-benzyl-1,2-O-isopropylidene-D-glucofuranose with dipotassium hydrogen phosphate yields the corresponding 6-phosphate, which, after acidic hydrolysis and periodate cleavage between C-1 and C-2, gives the stable 2-O-benzyl-D-arabinofuranose 5-phosphate. Removal of the benzyl group by hydrogenolysis affords the title compound. In view of the known instability of pentose
