[0092] (R)-3-(4-Dimethylamino-2-methoxy-phenyl)-pentanal (Table 1, entry 3): To a 2-dram vial equipped with a magnetic stir bar was added (2S,5S)-5-benzyl-2-tert-butyl-3-methylimidazolidin-4-one (24.6 mg, 0.100 mmol, 0.200 equiv), CH2Cl2 (0.50 ml), HCl (as a 4N solution in 1,4-dioxane, 25.0 uL, 0.100 mmol, 0.200 equiv), and N,N-dimethyl-m-anisidine (73.3 uL, 0.500 mmol, 1.00 equiv). The solution was cooled to -50o C. before pentenal (98.0 uL, 1.00 mmol, 2.00 equiv) was added. After 62 h, the reaction mixture was subjected directly to silica gel chromatography. Elution with 20% EtOAc in hexanes followed by concentration and removal of residual pentenal under vacuum afforded the product as a colorless oil in 68% yield (79.5 mg, 0.338 mmol); 88% ee. IR (film) 2959, 2926, 2871, 2839, 2800, 2721, 1718, 1616, 1569, 1517, 1351, 1237, 1136, 1034, 979.5, 812.9 cm-1;1H NMR (300 MHz, CDCl3) ?9.63 (t, J=2.8 Hz, 1H, CHO), 6.97 (d, J=8.2 Hz, 1H, ArH), 6.30 (dd, J=2.5, 8.3 Hz, 1H, ArH), 6.26 (d, J=2.5 Hz, 1H, ArH), 3.81 (s, 3H, OCH3), 3.40 (dt, J=7.3, 7.4 Hz, 1H, ArCH), 2.94 (s, 6H, N(CH3)2), 2.66 (dd, J=2.7, 7.4 Hz, 2H, CH2CO), 1.72-1.61 (m, 2H, CH2CH3), 0.83 (t, J=7.4 Hz, 3H, CH2CH3); 13C NMR (75 MHz, CDCl3) 203.8, 158.2, 150.6, 128.4, 119.8, 105.0, 96.5, 55.5, 49.7, 1.1, 34.9, 28.4, 12.4. HRMS (CI) exact mass calcd for (C14H21NO2) requires m/z 236.1650 for [M+H]+, found m/z 236.1649. [?]D=-18.9 (c=0.970, CHCl3). The enantiomeric ratio of the product was determined by HPLC analysis of the corresponding alcohol (obtained by NaBH4 reduction) using a Chiracel AD and AD guard column (3.0% ethanol/hexanes, 1 mL/min); S isomer tr=11.5 min, R isomer tr=12.4 min.
According to the analysis of related databases, 15799-79-8, the application of this compound in the production field has become more and more popular.
