  total of 47 flavanones were expediently synthesized via one-pot β-arylation of chromanones, a class of simple ketones possessing chemically unactivated β sites, with arylboronic acids via tandem palladium(II) catalysis. This reaction provides a novel route to various flavanones, including natural products such as naringenin trimethyl ether, in yields up to 92%.

These Pd(II) catalyses expediently provide a variety of flavones and flavanones from 2′-hydroxydihydrochalcones as common intermediates, depending on oxidants and additives, via discriminate oxidative cyclization sequences involving dehydrogenation, respectively, in a highly atom-economic

  Purpose. Aromatase inhibitors are known to prevent the conversion of androgens to estrogens and play a significant role in the treatment of estrogen dependent diseases such as breast cancer. Some flavonoids have been reported as potent aromatase inhibitors: therefore. in an effort to develop novel anti breast cancer agents. B ring substituted flavanones with a 7-methoxy group on A ring were synthesized and tested to assess their ability to inhibit aromatase activity and to determine the optimal B ring substitution pattern.Methods. A series of flavanones was prepared by cyclisation of 2'-hydroxychalcones previously obtained by Claisen-Schmidt condensation and the aromatase inhibitory activity or these compounds was investigated using human placental microsomes and radiolabeled [1.2,6,7-H-3]-androstenedione as substrate.Results. Almost all flavanones exhibited inhibitory effect on the aromatase activity but their potency was dependent on their B ring subtitution pattern. Hydroxylation at position 3' and/or 4' enhanced the anti-aromatase activity thus, 3'.4'-dihydroxy-7-methoxyflavanone was found to he twice more potent than aminoglutethimide. the first aromatase inhibitor clinically used.Conclusions. These results indicated that these flavanones could be considered as potential anti breast cancer agents through the inhibition of aromatase activity and allowed us to select some of these Compounds as skeleton for the development of flavonoid structurally-related aromatase inhibitors.
