  Facile Total Syntheses of Idarubicinone‐7‐β‐D‐glucuronide: Convenient Preparations of AB‐Ring Synthon Using Some Carboxylic Acid Derivatives

  摘要：

  Regiospecific syntheses of idarubicinone coupled with D-glucuronic acid are described. Cyclization of dimethoxybenzene with carboxylic acid derivatives in polyphosphoric acid (PPA) in one step afforded the naphthalenones 7, which were transformed to the (+/-)-idarubicinone 3b by general methods. Esterification of (+/-)-3b with (S)-(+)-O-acetylmandelic acid with subsequent separation and deprotection gave (+)-3b and (-)-3b. Reaction of separated two stereoisomers with acetobromo-alpha-D-glucuronic acid methyl ester respective followed by hydrolysis using lithium hydroxide and amberite cation exchange resin furnished two kinds of idarubicinone-7-beta-D-glucuronide (20 and 21) that are coupled at C-7 position of idarubicinone.
