反応手順
Ethyl acetoacetate (3.9g, 0.03 moles), parahexylbenzaldehyde (3.8g, 0.02 moles) and piperidine (3 drops) were stirred at room temperature for 20 hrs. and then stirred for 4 days at 70° C. Products A and B were separated and purified by silica gel chromatography. Structure assignments were supported by NMR, infrared and uv spectra and elemental analysis (302.4).
