title: Synthesis of 2-deoxy-beta-D-ribose 1-phosphate, NMR comparison and its enzymatic activity for structural elucidation of synthetic alpha-isomer.
abstract: 2-Deoxy-beta-D-ribose 1-phosphate (1) was synthesized in a stereoselective manner and isolated with no detectable contamination by its alpha-isomer (4). Explicit configuration of 4 was first determined by NMR comparison with 1 judging from NOE results and their coupling constants. Natural purine nucleoside phosphorylase (PNPase) did not recognize 1 and gave no products such as alpha- or beta-deoxynucleosides.
