Acid-Catalyzed Synthesis of Methylene-Bridged (S)-Tyrosine−Phenol Dimers
摘要:
The efficient synthesis of 2,2'-arylmethylene dimers from 3-hydroxymethyl or 3-methoxymethyl-5-halo-(S)-tyrosines and para-substituted phenols under acid-catalyzed reaction conditions using either conventional or microwave-assisted protocols is described.
