Participants

Reaction Steps

To a stirred solution of 4-diethoxyphosphoryl-1,7-bis(2-nitrobenzenesulfonyl)-1,4,7-triazacyclotetradecane (1.32 g, 1.87 mmol) and K2CO3 (654 mg, 4.73 mmol) in DMF (11 mL) under nitrogen was added dropwise a solution of thiophenol (0.15 mL, 1.46 mmol) in DMF (8 mL) over 1 h. The mixture was stirred for an additional 3 h and then concentrated in vacuo. The residue was partitioned between CHCl3 (50 mL) and H2O (25 mL). The aqueous phase was separated and extracted with CHCl3 (3×20 mL) and the combined organic extracts were dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography on basic alumina (CHCl3 then 3% MeOH/CHCl3) to give the title compound as a yellow oil (178 mg, 23%): 1H NMR (CDCl3) δ 1.31 (t, 6H, J=7.0 Hz), 1.40-1.67 (m, 10H), 2.65 (m, 2H), 2.78 (m, 2H), 3.12 (m, 2H), 3.26-3.37 (m, 4H), 3.48 (m, 2H), 3.97-4.09 (m, 4H), 7.61 (m, 1H), 7.68 (m, 2H), 8.06 (m, 1H).
