    • General Procedure To a solution of diazo bisphosphonate 1a (100 mg, 0.318 mmol) and alcohol (0.350 mmol) in 6 mL of anhyd toluene was added Cu(OTf)2 (1.2 mg, 0.003 mmol, The mixture was heated under reflux for 8 or 12 h and then evaporated under reduced pressure. The residue was purified directly by flash chromatography on silica column (acetone-CH 2Cl2, 1:1) to afford the desired product. All new compounds have been characterized by 1H NMR, 13C NMR, 31P NMR, IR, and mass spectroscopy. Selected Data: Compound 5b: 1H NMR (400 MHz, CDCl3, δ, 1.29 (t, J, 7.2 Hz, 6 H, 1.31 (t, J, 7.2 Hz, 6H, 4.04 (t, J, 17.8 Hz, 1 H, 4.08-4.20 (m, 8 H, 4.80 (s, 2 H, 7.26-7.38 (m, 5 H)ppm. 13C NMR (100 MHz, CDCl3, δ, 16.32-1641 (m, 63.16 (d, J, 3.0 Hz, 63.19 (d, J, 3.0 Hz, 63.31 d, J, 3.0 Hz, 63.34
