e (IIa-o), containing both electron-donor and electron-acceptor substituents in the phenoxyl part of the molecule. These compounds were obtained by the action of phosphorus chloride on the complex of the compound (Ia-o) with boron trifluoride etherate in dimethylformamide. The acylation of the compound (II) with acetic anhydride in the presence of pyridine gave the corresponding acetates (IIl).
为了开发具有兴奋和降血脂活性的物质,我们完成了 3-苯氧基-7-氢色酮 (IIa-o) 的合成,在分子的苯氧基部分包含电子供体和电子受体取代基. 这些化合物通过氯化磷对化合物(Ia-o)与三氟化硼醚合物在二甲基甲酰胺中的络合物的作用而获得。在吡啶存在下用乙酸酐酰化化合物(II)得到相应的乙酸酯(IIl)。
