Yield:3300-51-4 93%

Reaction Conditions:

with 1-phenylphospholane-1-oxide;1,3-diphenyl-disiloxane in tetrahydrofuran at 23; for 24 h;Staudinger Azide Reduction;Reagent/catalyst;Solvent;

Steps:

Additive-Free Catalytic Staudinger Reduction at Ambient Temperature; General Procedure

General procedure: To a 2-dram vial equipped with a stir bar were added all solid reagents(azide: 0.25 mmol, 1.0 equiv), 1a (4.5 mg, 0.025 mmol, 0.1equiv), THF (1 mL), all liquid reagents (azide: 0.25 mmol, 1.0 equiv),and then DPDS (57.5 mg, 0.25 mmol, 1.0 equiv). The reaction flaskwas sealed with a PTFE septum in the screwcap and the mixture wasstirred at 23 °C for 24 h. The mixture was diluted with acetone andthe vessel was washed with acetone (7.5 mL); this mixture was loadeddirectly onto silica gel (200 mg). Purification by flash column chromatography(EtOAc/hexanes, 40:60 with 1.5-5% Et3N) afforded amine products 4.
