Reaction Conditions:
for 0.25 h;Inert atmosphere;Reflux;
Steps:
General procedure: The appropriate o-hydroxybenzaldehyde (1 mmol) and ethyl(triphenylphosphoranylidene) acetate(1.2 mmol) were dissolved in N,N-diethylaniline (1.5 mL) and the resulting mixture was stirred under aN2 atmosphere and reflux for 15 min. The solvent was removed under reduced pressure (1 mmHg,52 °C) and the resulting brown oil was purified by column chromatography (petroleum ether-ethylacetate, 3:1).
