49% | With sodium hydride; In tetrahydrofuran; mineral oil; at 37℃; for 13h;Reflux; | General procedure: <strong>[6882-68-4]Sophoridin</strong>e(200 mg, 0.8 mmol) and 60% sodium hydride (806 mg, 20 mmol) into around-bottomed flask (50 mL) were resolved in anhydrous tetrahydrofuran (20mL). The solution was stirred and aldehyde (4 mmol) was added at 37 C andstirred for 1 h. The solution was then refluxed for 12 h. After cooling to roomtemperature, the mixture was pouredinto water (10 mL), acidified to pH=1~3 with 2N HCl and extracted with dichloromethane(3 × 40 mL). The aqueous phase was adjusted to pH=10~11 with 2N NaOH, and extracted with dichloromethane (3 × 40mL). The solvent was removed in vacuo, and the residue was purified by flashsilica gel column chromatography (petroleum ether/acetone, 10%) to afford 11-16. |
