A novel and selective method for the introduction of substituents at the 2-position of the isoflav-3-ene nucleus, utilising readily available 3-arylcoumarins as starting materials, is described. Thus, addition of a Grignard reagent to the corresponding phenyl acetal provided the desired 2-alkyl-, alkenyl-, or arylisoflav-3-enes. These compounds interact strongly with the estrogen receptor and show
描述了一种新颖的,选择性的方法,该方法利用容易获得的3-芳基香豆素作为原料,在异黄酮-3-烯核的2-位引入取代基。因此,向相应的苯基缩醛中加入格氏试剂可得到所需的2-烷基-,烯基-或芳基黄酮-3-烯。这些化合物与雌激素受体强烈相互作用,并根据2-取代基的性质显示雌激素或抗雌激素作用。
