3-Acetylbiphenyl-4-ol and -2-ol were condensed with substituted benzaldehydes to give respectively 5′-and 3′-phenyl-substituted chalcones (1a–k), which were cyclized to afford 6- and 8-phenylflavanones. The chalcones (1a–k) also gave the corresponding 6- and 8-phenylflavones via dibromides. The effects of the phenyl group on the spectral data are also discussed.
3-乙酰联苯-4-醇和-2-醇与取代的苯甲醛缩合分别得到5'-和3'-苯基取代的查耳酮(1a-k),将其环化得到6-和8-苯基黄烷酮。查耳酮 (1a-k) 还通过二溴化物生成相应的 6- 和 8- 苯基黄酮。还讨论了苯基对光谱数据的影响。
