    • The ratio of enantiomer 2e was determined by HPLC analysis after converting the azide to 1,4-disubstituted 1,2,3-triazole on treatment with phenylacetylene in the presence of CuSO4·5H2O and sodium ascorbate.

    • Typical experimental procedure is as follows (Table 2, Entry 5): to PhOPPh2 (0.60 mrnol) in dry toluene (0.30 mL) was added tri-methylsilylmethyl azide (0.60 mrnol) at rt under Ar atmosphere. After this mixture was stirred for 20min at 80 °C, alcohol 1f (0.20 mrnol) in dry toluene (0.60 mL) and TMSN3 (0.60 mmol) were added at rt. The reaction mixture was stirred at rt for 48 h and the crude product was purified by preparative TLC to afford the corresponding azide 2f (86% yield).
