  A Novel and Convenient Chemoselective Deprotection Method for Both Silyl and Acetyl Groups on Acidic Hydroxyl Groups Such as Phenol and Carboxylic Acid by Using a Nitrogen Organic Base, 1,1,3,3-Tetramethylguanidine

  摘要：

  [GRAPHICS]1,1,3,3-Tetramethylguanidine (TMG)(1), a nitrogen organic base, is a convenient and useful reagent for chemoselective deprotection of both silyl and acetyl groups on acidic hydroxyl groups such as phenol and carboxylic acid without affecting aliphatic silyl and acetyl groups. The chemoselectivity is dependent on the acidity of the hydroxyl group.

  The preparation and characterization of some novel 2- and 3-substituted-7-methoxy-4H-1-benzopyran-4-one are presented. The synthesized compounds were evaluated for their uterotrophic, antiuterotrophic and antiimplantation activities in mature female albino rats. 3-Benzyl-7-methoxy-4H-1-benzopyran-4-one (14) showed the highest uterotrophic activity (87%) based on dry uterine weight gain. The antifertility activity, as assessed by the post-coital antiimplantation activity test, was of weak potency for most compounds (14-29%). Among the products, the 2-(4'-methoxyphenyl)-7-methoxy-4H-1-benzopyran-4-one (19) exhibited the highest antiestrogenic activity of 65%. It also elicited 31% of the uterotrophic activity of estradiol.
