70% | With ammonium acetate; In butan-1-ol;Reflux; | General procedure: A mixture of appropriate aldehyde 2.40 g (1-15), 2.44 g ofmalonic acid and 3.54 g of ammonium acetate (1:1.1:2.3), in 200mLof the 1-butanol was refluxed for 1.5-2 h until the evolution of CO2ceased. The precipitate formed was filtered and washed withboiling 1-butanol (2 x 50 mL), boiling ethanol (2 x 50 mL) and100mL of water. Precipitates were dried at 80-100 C for 8-10 h.Purity of product was checked by TLC, and yield obtained about65-80% in each reaction. |
65% | To a 2 liter three-mouth flask in of hydroxy benzaldehyde (100 g, 0 . 82 μM), ammonia acetate (126 g, 1 . 64 μM) and volume than 97.5% of ethanol (1.2 L). 40 C when stirring 30 minutes; then adding malonic acid (170 g, 1 . 64 μM), heating reflux for 60 hours. After cooling to room temperature, filtering and separating the white solid, for the volume ratio of 1:1 of ethanol and water mixed solution (100 ml) washing, vacuum drying to obtain a white solid, compound 1 (88.8 g, 0 . 53 μM, 65%). |

With sodium acetate; acetic acid; at 100℃; for 1h; | 3-(4-Hydroxyphenyl)-3-(1H-pyrrol-1-yl)propanoic acid (55.1). At 100 C., 2,5-dimethoxytetrahydrofuran (8.5 mmol) was added to a mixture of <strong>[6049-54-3]3-amino-3-(4-hydroxyphenyl)propanoic acid</strong> (7.7 mmol) and sodium acetate (46 mmol) in acetic acid (34 mL). After stirring for 1 h, acetic acid was removed under reduced pressure. The residue was extracted with ethyl acetate (300 mL). The organic layer was washed with brine and dried over anhydrous Na2SO4 and concentrated. The residue was purified via column chromatography (10% methanol in dichloromethane) to compound 55.1. LC-MS (neg.) m/e: 230.2 (M-H). |
