Boc-Alkynylimine Equivalent Useful for the Synthesis of Propargylamine Derivatives

Experimental procedure2): To a solution of 1 (0.10 mmol) and diphenyl phosphate (2.5 mg, 0.010 mmol) in dichloromethane (2.0 mL) is added 3-phenylpropanal (0.30 mmol) at room temperature. After 1 is consumed, the reaction mixture is added CH3OH (2.0 mL) and NaBH4 (11 mg, 0.30 mmol) at 0 °C. After stirring for 2 h at 0 °C, the reaction mixture is quenched with water and extracted with EtOAc. The combined organic layers are washed with brine, dried over Na2SO4 and concentrated. The residue is purified by column chromatography on silica gel (eluting with hexane:EtOAc = 7:1, then toluene:EtOAc = 20:1) to afford the corresponding aminoalcohol in 50% yield.
