In(III)-Mediated Chemoselective Dehydrogenative Interaction of ClMe2SiH with Carboxylic Acids: Direct Chemo- and Regioselective Friedel−Crafts Acylation of Aromatic Ethers
摘要:
Chemoselective dehydrogenative interaction of ClMe2SiH with a carboxylic acid group in the presence of InX3 is reported. C-13 NMR investigation revealed the formation of PhCOOSi(Cl)Me-2 as the major transient intermediate. Chemo- and regioselective Friedel-Crafts acylation of aromatic ethers directly from carboxylic acids was established.

4-Methylenedioxy-l-(3-phenylpropionyl)benzene exhibits anti-inflammatory activity and has low toxicity [1]. Therefore, in order to study the relationship between chemical structure and pharmacological properties and to investigate novel pharmaceuticals, we have synthesized and studied some new structural analogs (IIa-d) of this ketone. 3,4-Polymethylenedioxy-l-(3-phenylpropionyl)benzenes IIa-d were synthesized by
