Participants

Reaction Steps

A mixture of 69.2 mg (0.210 mmol) of ethyl 3-amino-2-phenylpropyl(diethoxymethyl)phosphinate (Tetrahedron, 1989, 3787-3808) and 48.2 mg (0.221 mmol) of 4-octylbenzaldehyde in 1 mL of MeOH at rt was treated with 6.7 mg (0.105 mmol) of Na(CN)BH3. The resulting reaction mixture was stirred at rt for 16 hr. The reaction was quenched with 0.3 mL of 12 N HCl, then heated up to 60° C. for 5 hr. The mixture was cooled and concentrated. HPLC purification (LC-2) afforded 22 mg (26%) of the title compound. 1H NMR (500 MHz) (CD3OD) δ 0.88 (t, J=7.1, 3H), 1.26-1.30 (m, 10H), 1.58-1.61 (m, 2H), 2.01-2.17 (m, 2H), 2.62 (t, J=7.8, 2H), 3.20-3.23 (m, 1H),3.35-3.46 (m, 2H), 4.11 (s, 2H), 6.92 (d, J=535.4, 1H), 7.23-7.37 (m, 9H); LC-1: 3.31 min; ESI-MS 402 (M+H).
